Kilkenny (Irish: Cill Chainnigh [ˌciːl̠ʲ ˈxan̠ʲəj], meaning 'church of Cainnech') is a city in County Kilkenny, Ireland. It is located in the South-East Region and in the province of Leinster. It is built on both banks of the River Nore. The 2022 census gave the population of Kilkenny as 27,184, the thirteenth-largest urban center in Ireland.

Kilkenny is a tourist destination, and its environs include historic buildings such as Kilkenny Castle, St Canice's Cathedral and round tower, Rothe House, Shee Alms House, Black Abbey, St. Mary's Cathedral, The Tholsel, St. Francis Abbey, Grace's Castle, and St. John's Priory. Kilkenny is also known for its craft and design workshops, the Watergate Theatre, public gardens and museums. Annual events include Kilkenny Arts Festival, the Cat Laughs comedy festival and music at the Kilkenny Roots Festival.

Kilkenny began with an early 6th-century ecclesiastical foundation within the Kingdom of Ossory. Following the 12th-century Norman invasion of Ireland, Kilkenny Castle and a series of walls were built to protect the burghers of what became a Norman merchant town. William Marshall, Lord of Leinster, gave Kilkenny a charter as a town in 1207. By the late 13th century, Kilkenny was under Hiberno-Norman control. The Statutes of Kilkenny, passed at Kilkenny in 1367, aimed to curb the decline of the Hiberno-Norman Lordship of Ireland. In 1609, King James I of England granted Kilkenny a Royal Charter, giving it the status of a city. Following the Irish Rebellion of 1641, the Irish Catholic Confederation, also known as the "Confederation of Kilkenny", was based in Kilkenny and lasted until the Cromwellian conquest of Ireland in 1649. From 1840 onwards, Kilkenny has not been administered as a city under local government law, but the Local Government Reform Act 2014 provides for "the continued use of the description city".

Kilkenny was a brewing centre from the late 17th century, and still houses a number of breweries. The Heritage Council offices are at Church Lane in the former Bishop's Palace. The seat of the Roman Catholic Bishop of Ossory is at St Mary's Cathedral and the Church of Ireland Bishop of Cashel and Ossory is at St Canice's Cathedral.

Kilkenny is the anglicised version of the Irish Cill Chainnigh, meaning Cell/Church of Cainneach or Canice. This relates to a church built in honour of St. Canice, an Ulsterman, on the hill now containing St. Canice's Cathedral and the round tower. This seems to be the first major settlement. The early Christian origin of the round tower suggests an early ecclesiastical foundation at Kilkenny.

Ceall-Cainnigh was for the most part burned.

— Four Masters, Annals of the Four Masters, 1085.

The Annals of the Four Masters recorded Kilkenny in 1085. Prior to this time the early 6th-century territory was known as Osraighe, referring to the whole district or the capital. The Four Masters entry was the first instance where the capital was called Ceall-Cainnigh (modernised Kilkenny). Cill Chainnigh was a major monastic centre from at least the eighth century. There is no mention of Cill Chainnigh in the lives of Cainnech of Aghaboe, Ciarán of Saighir or any of the early annals of Ireland suggesting that Cill Chainnigh was not of ancient civil importance.

Kilkenny's foundation began with an early 6th-century ecclesiastical settlement, with a church built in honour of St. Canice. Now St. Canice's Cathedral, this was a major monastic centre from at least the 8th century. The Annals of the Four Masters recorded the first reference Cill Chainnigh in 1085. Prehistoric activity has been recorded, suggesting intermittent settlement activity in the area in the Mesolithic and Bronze Age. Information on the history of Kilkenny can be found in newspapers, photographs, letters, drawings, manuscripts and archaeology. Kilkenny is documented in manuscripts from the 13th century onwards and one of the most important of these is Liber Primus Kilkenniensis.

The Kings of Ossory, O'Carrolls and Fitzpatricks, had residence around Cill Chainnigh. The seat of the diocese of Kingdom of Osraige was moved from Aghaboe to Cill Chainnigh. Following the Norman invasion of Ireland, Richard Strongbow, as Lord of Leinster, established a castle near modern-day Kilkenny Castle. William Marshall began the development of the town of Kilkenny and a series of walls to protect the burghers. By the late 13th century, Kilkenny was under Norman-Irish control. The original ecclesiastical centre at St. Canice's Cathedral became known as Irishtown and the Anglo-Norman borough inside the wall came to be known as Hightown.

Kilkenny was the site of Ireland's earliest recorded witch trial. Occurring in 1324 and instigated by the then Bishop of Ossory, Richard de Ledrede, the trial involved Dame Alice de Kyteler and her servant Petronella de Meath. Petronella would be the first person recorded in Ireland to be burned alive at the stake for witchcraft, after Dame Alice presumably fled the country. This trial was also one of the earliest recorded witch burnings in Europe and inspires much folklore about the possibility of the ghosts of Alice and Petronella haunting downtown Kilkenny. Alice's house, Kyteler's Inn, still stands and is now a pub.

The Hiberno-Norman presence in Kilkenny was deeply shaken by the Black Death, which arrived in 1348. The Statutes of Kilkenny passed at Kilkenny in 1367, aimed to curb the decline of the Hiberno-Norman Lordship of Ireland. In 1609, King James I of England granted Kilkenny a Royal Charter giving it the status of a city. Following the Rebellion of 1641, the Irish Catholic Confederation, also known as the "Confederation of Kilkenny", was based in Kilkenny and lasted until the Cromwellian conquest of Ireland in 1649. James II of England spent most of the winter months from November 1689 until January 1690 at Kilkenny, residing in the castle.

Stephens Barracks, built in the years following the 1798 Rebellion, was completed between 1800 and 1803.

The Kilkenny Design Workshops were opened in 1965 and in 1967 the Marquess of Ormonde presented Kilkenny Castle to the people of Kilkenny. Today, it has a lively cultural scene, with annual events including the Kilkenny Arts Week Festival in the last two weeks of August, and the Cat Laughs Comedy Festival at the beginning of June. Kilkenny is also where the Irish ale, Smithwick's, was first brewed. Kilkenny is referred to as the Marble City, and people from Kilkenny are often referred to as 'Cats'. The seat of the Roman Catholic Bishop of Ossory is at St. Mary's Cathedral and the Church of Ireland Bishop of Cashel and Ossory is at St. Canice's Cathedral.

Kilkenny is situated in the Nore Valley on both banks of the River Nore, at the centre of County Kilkenny in the province of Leinster in the south-east of Ireland. It is 117 kilometres (73 mi) away the capital Dublin and 48 kilometres (30 mi) north from the nearest city Waterford. Wexford is 80 kilometres (50 mi) to the south-east and Limerick is 122 kilometres (76 mi) to the west. The elevation is 60 metres (200 ft) above mean sea level. The area of Kilkenny borough is 3.74 square kilometres (1.44 sq mi). The first edition of the Ordnance Survey map for Kilkenny was in 1837 and is held by the County Library.

The climate of Kilkenny, like the climate of Ireland, is a changeable oceanic climate with few extremes. It is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system. Kilkenny lies in plant Hardiness zone 9. At the centre of the county, Kilkenny is in a sheltered location, 66 kilometres (41 mi) inland and is surrounded by hills over 200 metres (660 ft), which ensures that it is not a windy location. The highest wind gust of 77 knots, from a south-west direction, was recorded on 12 January 1974.

Kilkenny is generally representative of wide river valleys in the region with low temperatures on cloudless nights, and is significant in that it records some of the highest summer and lowest winter temperatures in Ireland. The highest air temperature ever recorded in Ireland was 33.3 °C (91.9 °F), at Kilkenny Castle on 26 June 1887.

The Met Éireann Kilkenny Weather Observing Station, 2 km north-west of the centre of Kilkenny, on the Duningstown Road, opened in May 1957, and observations ceased in April 2008. A climatological station is currently in operation within 1 km of the old site, and as of March 2010, was providing live weather data to the general public and climate data to Met Éireann. Extremes recorded at the station include the highest air temperature of 31.5 °C (88.7 °F) on 29 June 1976, the lowest air temperature of −14.1 °C (6.6 °F) on 2 January 1979 and the lowest ground temperature of −18.1 °C (−0.6 °F) on 12 January 1982.

The warmest and sunniest month on record in Kilkenny was August 1995 with a total of 274.9 hours sunshine and very high temperatures throughout. The maximum daily sunshine was 16.3 hours on 18 June 1978. The overall trend in temperatures has been on the rise with a marked increase from 1988 onwards. Annual temperatures are running over 0.5 degrees or 0.9°F above 20th century levels.

The maximum daily rainfall recorded at Kilkenny station was 66.4 millimetres (2.61 in) on 17 July 1983. The late 1950s and early 1960s were wet but rainfall had been steady throughout the century. 2002 was a very wet year and since 2005 annual rainfall has been increasing steadily, with 2009 being the wettest year since records commenced in 1958.

The majority of the population of Kilkenny live outside the borough's boundary. The urban centre of Kilkenny, as defined by the census, had a population of 27,184 in 2022.

Changes as of the 2006 census, by the Central Statistics Office, Kilkenny Town Borough had a population of 8,661 which was an increase of 70 persons over the 2002 figure of 8,591 or 0.8%. The Town Environs had a population of 13,518 which was an increase of 1347 persons over the 2002 figure of 12,144 or 11.3%. Overall both the Borough & Environs had a population of 22,179 in 2006 which was an increase of 1444 persons over the 2002 figure of 20,735 or 7.0%. People from Kilkenny are often referred to as 'Cats'.

Disposable household income per person as of 2005 was €18,032 and the index of disposable household was 89.4.

Kilkenny is multilingual but predominantly English-speaking, with Irish being the second most commonly spoken language. In recent decades, with the increase of immigration on an all-Ireland basis, many more languages have been introduced into Kilkenny.

The main religion is Catholicism, however, there are Church of Ireland, Presbyterian, Methodist, Jewish and other religious traditions living in Kilkenny.

Kilkenny is now administered as part of County Kilkenny. The local electoral area of Kilkenny contains the electoral divisions of Dunmore, Kilkenny No. 1 Urban, Kilkenny No. 2 Urban, Kilkenny Rural and St. Canice, and elects 7 of the 24 members of Kilkenny County Council. This area is defined as the Municipal District of Kilkenny City. Local government bodies in Kilkenny have responsibility for such matters as planning, roads, sanitation and libraries and are governed by the Local Government Acts 1925 to 2019, the principal Act being the Local Government Act 2001.

Kilkenny's first council was elected in 1231. From the 13th century to the end of the 16th, the chief magistrate was known as the sovereign, and since then as the mayor. It was granted a royal charter as a city in 1609 by James I of England and Ireland. This was a county corporate which included the borough of Irishtown, which fell within the city. The borough corporation established under the Municipal Corporations (Ireland) Act 1840 is a successor to both the corporation established under this charter and of the borough of Irishtown. In 1899, under the Local Government (Ireland) Act 1898, the area became an urban district, but its council retained the style of a borough corporation. In 2002, under the Local Government Act 2001, Kilkenny Borough Corporation became a borough council. On 1 June 2014, under the Local Government Reform Act 2014, the borough council was dissolved and administration of the town was amalgamated with Kilkenny County Council.

County Kilkenny is part of the Southern Region. It is part of the Carlow–Kilkenny Dáil constituency and the South European Parliament constituency.

In the Irish House of Commons, both Kilkenny City and the bishop's borough of St Canice (or Irishtown) were represented with two MPs each. From 1801, following the Acts of Union 1800, Kilkenny City was represented in the United Kingdom House of Commons by one MP from 1801 to 1918, and as part of North Kilkenny from 1918 to 1922. In 1921, the Carlow–Kilkenny Dáil constituency was created. This continued until 1937, when there was a separate Kilkenny constituency, but from 1948 there has been a continuous constituency of Carlow–Kilkenny.

While the present-day settlement is administered as a municipal district, the appellation "city" is an emotive subject in Kilkenny. Historically, city status in the United Kingdom, and before that in the Kingdom of Ireland, was a ceremonial designation awarded by the crown. It carried more prestige than the alternative municipal titles "borough" or "town", but gave no additional legal powers (the qualifying factor was the presence of a cathedral, resulting in some very small cities such as Wells, with a population 12,000 as of 2018 and St Davids, with a population of 1,841 as of 2011). A city in Irish law has special legal meaning with corresponding powers for local government. From a local government perspective, Kilkenny has not been administered as a city since at least 1840. The present-day legal, political and administrative jurisdictions in Ireland are set out in the Local Government Act 2001, as amended by the Local Government Reform Act 2014.

In 2002, under the Local Government Act 2001, the former five county boroughs were redesignated as cities. At the same time, the historic city status of Kilkenny was acknowledged in law. When this legislation was being debated, local TDs Phil Hogan and John McGuinness successfully lobbied that Kilkenny could continue to be referred to as a "city". Accordingly, a clause was added to the 2001 bill:

the continued use of the description city in relation to Kilkenny, to the extent that that description was used before the establishment day.

— Local Government Act 2001

It remains both common and permissible in law to describe Kilkenny as a city; section 10(6) of the 2001 Act, as amended by the 2014 Act, provides that "the continued use of the description city in relation to Kilkenny, to the extent that that description was used before 1 January 2002 and is not otherwise inconsistent with this Act".

As of 2014, Kilkenny does not have an administration separate from the county. However, under Local Government Reform Act 2014, the municipal district is distinctly acknowledged as "the Municipal District of Kilkenny City".

Kilkenny's architectural heritage is represented through a number of historical buildings and landmarks. Kilkenny is a well-preserved medieval town and is dominated by both Kilkenny Castle and St. Canice's Cathedral and round tower.

Surviving examples of the city's medieval architecture include Kilkenny Castle and parts of the Kilkenny City Walls. These walls define the extent, layout and status of the medieval town. The town grew from a monastic settlement to a thriving Norman merchant town in the Middle Ages. St. Canice's Cathedral and round tower are an example of the monastic settlement. Rothe House on Parliament Street is an example of an Elizabethan merchant townhouse located on the only completely surviving burgage plot in Ireland. It also features a restored 17th-century garden on an area of half an acre behind the house, complete with herbs, vegetables and an orchard.

The black stone with decorative white fossils that forms the backbone of many of Kilkenny's fine buildings was quarried locally, particularly from the quarry located 1.6 km south of the town on the R700. Kilkenny marble was used for the plinth of the new tomb of Richard III in Leicester Cathedral in England.

Visitor attractions in Kilkenny and its environs include Kilkenny Castle and Gardens including the Butler Gallery, St. Canice's Cathedral and round tower, Rothe House and Garden, Shee Alms House, Kilkenny Courthouse, St. Mary's Cathedral, The Tholsel, the Dominican Black Abbey, St. John's Church, Butler House, Kilkenny 'Slips' and St. Francis Abbey Brewery. Gardens include the Castle Rose Garden, Rothe House Garden, the Famine Memorial Garden and the garden of Butler House.

In the county other attractions include Kells Priory, Jerpoint Abbey, Dunmore Caves, Woodstock Estate and Jenkinstown Park.

Local Kilkenny marble or black marble was used to decorate many of the city's buildings, and Kilkenny referred to the "Marble City" for this reason.

Kilkenny Castle in Kilkenny city was the seat of the Butler family. (Formerly the family name was FitzWalter.) The castle was sold to the local Castle Restoration Committee in the middle of the 20th century for £50. Shortly afterwards it was handed over to the State, and has since been refurbished and is open to visitors. Part of the collection of the National Art Gallery is on display in the castle. There are ornamental gardens on the northwest side of the castle, and extensive land and gardens to the front. It has become one of the most visited tourist sites in Ireland.

The first stone castle was begun in 1204 by William Marshall the site was completed in 1213; it was a symbol of Norman occupation and in its original thirteenth-century condition it would have formed an important element of the defences of the town. There were four large circular corner towers and a massive ditch, part of which can still be seen today on the Parade. This was a square-shaped castle with towers at each corner; three of these original four towers survive to this day.

Kilkenny Walls protected the medieval town of Kilkenny. The town was surrounded by walls with regular towers and gates. Remnants of the Town Walls survive such as Talbot Tower (1207), which is also known as Talbot's Bastion or Castle. It is the larger of the two surviving towers of the defences of the medieval High town of Kilkenny. There are walls on Abbey Street, and the adjoining Black Freren Gate is the only surviving gate/access remaining on the High town Circuit into the old city. A wall also runs through the brewery's grounds beside St. Francis Abbey.

The Kilkenny City Walls Conservation Plan is a plan by the inhabitants of Kilkenny, Kilkenny Borough Council, the Department of Environment, Heritage and Local Government, An Taisce, The Kilkenny Archaeological Society and The Heritage Council to ensure the long-term survival of the city's walls.

St Canice's Cathedral, also known as Kilkenny Cathedral, present building dates from the 13th century and is the second longest cathedral in Ireland. The cathedral is named after Saint Canice, who also gave his name to the town.

Cruciform, the cathedral was built in the Early English, or English Gothic, style of architecture, of limestone, with a low central tower supported on black marble columns. The exterior walls, apart from the gables, are embattled, and there are two small spires at the west end. The cathedral is seventy-five yards long, and its width along the transepts is forty-one yards.

Beside the cathedral stands a 100 ft 9th century round tower. St. Canice's tower is an excellent example of a well-preserved early Christian (9th century) Round Tower. Accessible only by a steep set of internal ladders, it may once have been both a watchtower and a refuge, and the summit gives a good view of Kilkenny and the countryside around. The hill on which the cathedral stands is believed to be the centre of the first major settlement at Kilkenny, and the round tower suggests an early ecclesiastical foundation.

Dominican Black Abbey was founded in 1225, and lying just off Parliament Street.

Kilkenny has four main bridges — Green's Bridge, John's Bridge, the Ossory Bridge and the St Francis Bridge — and two pedestrian/cycle bridges — the Lady Desart Bridge and the Ossory Pedestrian Bridge. Each of the bridges spans the River Nore.

Green's Bridge, also known as the 'Great Bridge of Kilkenny', crosses the River Nore in St. Canices Parish in the townland of Gardens, and is an important element of the architectural heritage of Kilkenny City. First built before 1200, the bridge has been rebuilt several times since the twelfth century due to flooding, including the great floods of 1487 and 1763. The present-day bridge was built in 1766 after the 'Great Flood of 1763'. It was built by William Colles (c. 1710–70) to designs prepared by George Smith (1763–67), a pupil of George Semple (c. 1700–82).

John's Bridge connects John Street to Rose Inn Street in Kilkenny City. It was first built after 1200, and has been called 'John's Bridge' since the Middle Ages. It has also been rebuilt many times since the twelfth century due to flooding. During the flood of 1763, people gathered on John's Bridge after Green's Bridge collapsed. John's Bridge also collapsed, and sixteen people died. The present-day John's Bridge was completed in 1910 and spans 140 ft (43 m) across the River Nore. It was reputedly, at the time it was completed, the longest single-span reinforced bridge in Ireland or Britain. The design was by Mouchel & Partners using the Hennebique system of reinforcement. The arch consists of three ribs, tapering from 2 ft 6 in (0.76 m) to 2 ft (0.61 m) deep. The traverse deck beams are each 2 ft (0.61 m) deep.

The Ossory Bridge, linking the ring road, was completed in 1984 and features an inlaid sculpture. St Francis Bridge was opened in May 2017, and forms part of the Kilkenny Central Access Scheme. The scheme and the proposed building of the new bridge was the subject of some debate and protest in Kilkenny in 2014.

Lady Desart Bridge and Ossory Pedestrian bridge are the city's two pedestrian/cycle bridges. Lady Desart Bridge was opened in January 2014 and links John's Quay and Bateman Quay and is located between John's Bridge and Green's Bridge. The Ossory Pedestrian bridge, located underneath the main Ossory bridge, links the Canal Walk on one side of the River Nore to the Lacken Walk on the other side.

The Old Woollen Mills was built in the 1800s and is located on the north side of the city, on Bleach Road. It was one of the largest employers in the area; the site covers 90,000 square feet (8,400 m) and has more than a mile of river frontage onto the Nore. Among its many features is a freestanding red brick chimney, erected in 1905. An architectural salvage and antique yard, Kilkenny Architectural Salvage, is currently located on the site.

Kilkenny is a popular tourist destination in the South-East Region of Ireland. Its art galleries, historic buildings, craft and design workshops, theatre, comedy, public gardens and museums are some of the main reasons Kilkenny has become one of Ireland's most visited towns and a base from which to explore the surrounding countryside.

Points of cultural interest in the area include Kilkenny Castle, St. Canice's Cathedral and round tower, Rothe House, St. Mary's Cathedral, Kells Priory, Kilkenny Town Hall, Black Abbey and Butler Gallery. The latter re-opened in August 2020, having moved to a new location in Evan's Home from the former basement kitchen of Kilkenny Castle.

St Canice's Cathedral sometimes hosts classical musicians and choirs. The Kilkenny Choir and a gospel choir have performed in churches throughout the town. Groups like Ex Cathedra have played during the Kilkenny Arts Festival. Cleere's pub and theatre on Parliament Street are known for touring Irish and international bands including indie, jazz and blues. They also have a traditional music session every Monday night, as does Ryan's on Friary Street on Thursdays.

Kilkenny had a tradition of dramatic performance going back to 1366 when the Dublin company set up in Kilkenny. Henry Burkhead printed a play in Kilkenny, Cola's Fury, or Lirenda's Misery (1645), dealing with events of the Irish Rebellion of 1641 from an English standpoint. It was a blatantly political work with the Lirenda of the title being an anagram of Ireland. In 1642, as a result of the English Civil War, Dublin Royalists were forced to flee the city. Many of them went to Kilkenny to join a confederacy of Old English and Irish that formed in that city.

In 1802 Sir Richard and Sir John Power of Kilfane established the Kilkenny Private Theatre.

The Watergate Theatre in Kilkenny is a centre for the performing and visual arts. It provides a varied programme of professional and amateur dramatics, classical and contemporary music, opera and dance, together with exhibitions of paintings and photographs.

The city has a history of brewing and was home to St. Francis Abbey Brewery which was founded in the early 18th century by Messrs Cole and Smithwick. The Guinness Ireland Group owned this brewery since the 1960s. At the beginning of the 21st century, Guinness merged with Grand Metropolitan plc to form Diageo, the world's largest alcoholic beverage business, and the brewery became part of Diageo Global Supply. In its final years, Smithwick's Ale formed only a small percentage of production there. Another product was Kilkenny ale, a close relation of Smithwick's ale. Some 80% of the beer produced at the brewery was Budweiser, a brand not owned by Diageo, but produced under licence.

In 1966 over 30 local creameries created by local farmers joined with other small rural co-operative societies throughout County Kilkenny and some neighbouring counties, and together with Unigate Limited support, formed the Avonmore Creameries Federation. According to the Glanbia Collections in Kilkenny Archives at St Kieran's College, Kilkenny, the Avonmore Coop brand was created through the merger of several dozen village creameries throughout County Kilkenny. Realising the benefits of increased scale and greater diversification in the 1960s, they saw the need for an amalgamation of many small, locally focused co-operatives across Ireland. It led to the construction of a new multi-purpose Avonmore dairy plant facility in Ballyragget, County Kilkenny, a plant they claimed was the biggest food processing facility in Europe at that time. Today that giant global entity is known as Glanbia. Glanbia has its origins in the Irish agricultural co-operative movement that evolved over the last century, ever since first Irish Co-operative founded by Horace Plunkett in 1889. Today Glanbia has operations in 34 countries and is exporting to more than 100 countries worldwide. Glanbia is ranked by revenue (2010 figures) in the top 100 Cooperatives, No 98 in the world and No 1 in Ireland by the International Co-operative Alliance, the global apex organisation of co-operatives worldwide.
