Dunoon (/duˈnuːn/; Scottish Gaelic: Dùn Omhain [t̪un ˈo.ɪɲ]) is the main town on the Cowal Peninsula in the south of Argyll and Bute, west of Scotland. It is located on the western shore of the upper Firth of Clyde, to the south of the Holy Loch and to the north of Innellan. As well as forming part of the council area of Argyll and Bute, Dunoon also has its own community council. Dunoon was a burgh until 1976.

The early history of Dunoon often revolves around two feuding clans: the Lamonts and the Campbells. The town was a popular destination when travel by steamships was common around the Firth of Clyde; Glaswegians described this as going doon the watter. This diminished, and many holidaymakers started to go elsewhere as roads and railways improved and the popularity of overseas travel increased.

In 1961, during the height of the Cold War, Dunoon became a garrison town to the United States Navy. In 1992, shortly after the dissolution of the Soviet Union, they closed their Holy Loch base in Sandbank, and neighbouring Dunoon suffered an economic downturn. Since the base's closure, the town and surrounding area are again turning to tourism, marketing to outdoor enthusiasts and wildlife lovers, as well as promoting festivals and competitions. The largest annual event held in the town is the Cowal Highland Gathering, which has been held since 1894. The Royal National Mòd has also been held in the town.

Dunoon Castle was built on a small, partly artificial, conical hill beside the Firth of Clyde in the 12th century, of which low walls remain. It eventually became a royal castle with the Earls of Argyll (Campbells) as hereditary keepers, paying a nominal rent of a single red rose to the sovereign. Mary, Queen of Scots, visited Dunoon Castle on 26 July 1563 and granted several charters during her visit. In 1646 the Dunoon massacre of members of Clan Lamont by members of Clan Campbell took place. The castle was destroyed during Argyll's Rising, a rebellion in 1685 against James VII.

In the early 19th century, the town's main street, Argyll Street, stopped at Moir Street. Instead of continuing to Dunoon Pier, it turned right at today's Sinbad's Bar. Before Dunoon Burgh Hall was built, beginning in 1873, the land was an open field, owned by James MacArthur Moir, leading to an area known as the Gallowhill. There were no streets and houses between Argyll Street and Edward Street. Argyll Street, roughly as it is seen today, was completed by 1870. Moir donated some of his land for the building of the Burgh Hall, but he did not get to see its completion; he died by suicide in 1872.

Dunoon in the 21st century is overlaid with the ghost of a town which, in 1885, possessed two banks, 21 insurance agencies, 10 hotels, a gas company, two bowling greens, three weekly papers, the West of Scotland Convalescent Sea-side Homes (complete with Romanesque hydropathic spa) and the lavishly appointed second homes of some of Scotland's most successful people.

— Saving the Hall (Jay Merrick, 2017)

The two banks mentioned above were the Union Bank of Scotland and the City of Glasgow Bank. The hydropathic spa, meanwhile, was "an elegant new baths building, named Ardvullin, erected a little to the north of the village as a hydropathic establishment, where baths - hot, cold, artificial salt, and Turkish — may be had at moderate charges."

Many of the town's early villas had their own private bathing ground or boxes.

The best bathing place for ladies is the West Bay. Gentlemen's bathing places: Rocks, foot of Castle Hill, deep at all states of the tide. Sand: beyond Baugie Burn, beginning of Bullwood, shallow and sandy. Rocks: behind Argyll Hotel, available only at high water. Kirn Pier and Hunters Quay, deep water.

— Colegate's Guide to Dunoon, Kirn, and Hunter's Quay (John Colegate, 1868)

The population of the united parishes of Dunoon and Kilmun in 1861 was 5,444; in 1866 the estimated population of Dunoon, from Baugie Burn to Hunters Quay, was 3,000.

During the World Wars, as the main part of the Firth of Clyde defences, the Cloch Point-to-Dunoon anti-submarine boom was anchored to the shore in Dunoon below Castle Hill. A Palmerston Fort and camp at Ardhallow Battery in the south of the town provided one of the coastal defence gun emplacements that covered the anti-submarine boom and Firth of Clyde waters. There also was a gun emplacement atop Castle Hill.

In 1961, as the Cold War intensified, the Holy Loch's importance grew when the U.S. Navy submarine tender USS Proteus brought Polaris ballistic missiles, nuclear submarines to the Firth of Clyde at Sandbank. Campaign for Nuclear Disarmament protesters drew this to the public's attention. Holy Loch was, for thirty years, the home port of U.S. Navy Submarine Squadron 14 and Dunoon, therefore, became a garrison town.

In 1991, the Holy Loch base was deemed unnecessary following the demise of the Soviet Union and was subsequently withdrawn. The last submarine tender to be based there, the USS Simon Lake, left Holy Loch in March 1992, leading to a major and continuing downturn in the local economy.

In May 2012, Dunoon and Campbeltown were jointly named as the rural places in Scotland most vulnerable to a downturn in a report by the Scottish Agricultural College looking at ninety places.

Dunoon is represented in the Scottish Parliament by Jenni Minto, of the Scottish National Party (SNP), who holds the Argyll and Bute seat. Dunoon also lies within the Highlands and Islands electoral region, from which a further seven additional members are elected to produce a form of proportional representation for the region as a whole.

In the House of Commons, Dunoon is represented by the SNP's Brendan O'Hara, who holds a seat also titled Argyll and Bute, although this seat has different boundaries from the one used for the Scottish Parliament.

Argyll and Bute Council is the Local Authority for the council area covering Dunoon. It is one of 32 such council areas across Scotland. Dunoon forms a single ward for elections to Argyll and Bute Council, electing three councillors via the single transferable vote system. At the last election, held in May 2017, one independent and one member from each of the SNP and the Conservatives was elected to represent the town.

Dunoon has a community council, whose primary role is to represent the views of the community to the Local Authority and other public bodies.

Today, there are a number of churches in Dunoon, including:

Church of Scotland: St John's Church

Roman Catholic: Our Lady and St Mun's Church

Other churches:

There is evidence of an episcopal seat at Dunoon from the latter part of the 15th century. No remains of the Bishop's Palace now exist, the site is now occupied by the playground of Dunoon Primary School, between Hillfoot Street and Kirk Street.

Defunct religious buildings

Dunoon's Victorian pier was extended to the current structure between 1896 and 1898. It was shortened to allow the building of a breakwater in 2005, just to the south of the pier. As well as protecting the pier and its architecture from storm surges, a new link span was installed alongside the breakwater. This was to allow the berthing and loading of roll-on/roll-off ferries instead of the side-loading ferries that used to serve the pier. A tender to serve the new link-span between two interested parties, Caledonian MacBrayne and Western Ferries, came to nothing. Prior to June 2011, the pier was in daily use by Caledonian MacBrayne, who ran a regular foot passenger and car-ferry service to Gourock. However, after June 2011, a renewed tendering process produced a passenger-only ferry service (Argyll Ferries, owned by Caledonian MacBrayne) using the breakwater for berthing. On 1 September 2004, during the construction of the breakwater, the cargo vessel Jackie Moon (82 metres in length) ran aground on the breakwater, with six people on board. Since the breakwater became operational in June 2011, Argyll Ferries operate from this docking facility. The Waverley struck the breakwater on 26 June 2009, with some 700 people on board. The pier was partially refurbished by Argyll and Bute Council during 2015. Now containing meeting rooms, it is purely a tourist attraction.

Dunoon Burgh Hall opened in 1874, the work of notable Glasgow architect Robert Alexander Bryden, who is buried in Dunoon Cemetery, a mile to the north. It is a Scottish baronial-style building that housed the municipal offices and had a hall accommodating 500 people. The Category B listed building re-opened in June 2017, and is a fully accessible venue for exhibitions, performances and gatherings. Alongside a gallery and theatre, the venue offers creative workshop space, a garden and a café.

On 20 August 2021, several Argyll Street buildings were destroyed in an arson attack.

Mary Campbell, also known as "Highland Mary" and "Bonny Mary O' Argyll", was born at Auchamore Farm in Dunoon. She had a relationship with the bard Robert Burns. The Highland Mary statue was erected in 1896; it is prominently sited on Castle Hill, overlooking the breakwater in Dunoon.The statue is a scheduled monument (LB26437).

The war memorial of Dunoon is located in the Castle Gardens, overlooking the pier.

The Queen's Hall is the town's major multi-function hall complex. It is situated opposite the head of the Victorian pier and built in 1958. It was officially opened by Queen Elizabeth II on 11 August 1958. The building houses four function suites and a large main hall. The main hall has a stage with professional sound and lighting equipment, and attracted popular acts such as Pink Floyd, Blur, the Saw Doctors, David Gray, Morrissey, the Red Hot Chilli Pipers, Primal Scream and comedians Kevin Bridges, Bill Bailey and Roy Chubby Brown. In late 2015 the Queen's Hall was closed to enable a major refurbishment. In December 2016, it was announced that the refurbishment would not commence until January 2017. The Queens Hall reopened in August 2018.

Riverside Swim and Health Centre, including an indoor pool (25m long) and associated facilities, located on Alexandra Parade.

Dunoon Library is situated in the rebuilt Queens Hall at the Castle Gardens.

A small group of rocks, known as the Gantocks, lie off the coast at Dunoon. The navigation beacon on the Gantocks in the Firth of Clyde is close to the coast at Dunoon. It was built in 1886.

The Clan Lamont Memorial, also known as the Dunoon Massacre Memorial, is on Tom-A-Mhoid Road close to Castle Hill. It was dedicated in 1906 and commemorates the Dunoon massacre of 1646, when the Campbell Clan attacked the Lamont Clan, killing over 200 people.

Local wildlife includes seals, otters, dolphins, basking sharks, roe deer, red deer, red squirrels, and many species of birds.

The Castle House Museum opens during the summer season. It holds historical information and displays for Dunoon and the Cowal peninsula.

The Cowal Highland Gathering, established in 1894, attracts contestants and spectators from all over the world. It is held annually over the final weekend in August at Dunoon Stadium.

Cowal Open Studios, held over a fortnight in September, gives the opportunity to visit the studios of artists around Dunoon and Cowal.

Cowalfest celebrates the outdoors activities like rambling around Dunoon for ten days in October.

Since the 1930s Dunoon has hosted the Royal National Mòd a number of times – 1930, 1950, 1968, 1994, 2000, 2006, 2012 and 2018.

In 2013, the first Dunoon Film Festival was held over three days and opened with first public screening of Your Cheatin' Heart, a series made by the BBC that had last been shown on television in 1990.

Dunoon is accessible by direct land and sea routes and indirectly by rail at Gourock.

Modern Dunoon owes its existence to steam power; as late as 1822 there were only three or four slated houses, the rest of the residences being traditional Highland cottages. In the New Statistical Account, the MP James Ewing from Glasgow is named as beginning the expansion of the village when he built Castle House close to Dunoon Castle. The growth of the village increased from that time, paralleling the engineering-led growth of the steamers. Other infrastructural advances also helped like the construction of a 130-yard-long (120-metre) jetty in 1835. From 1812 to the late 1960s, thousands of holiday-makers travelled doon the watter from Glasgow and industrial Lanarkshire to Dunoon and to numerous other town piers on the Firth of Clyde.

Trails (walks, running and mountain biking) thread through the hills surrounding Dunoon. Corlarach Hill has waymarked routes for walkers, mountain biking and horse riders. These trails are located next to the Bishop's Glen.

Puck's Glen is a popular short walk set in the hills close to Benmore Botanic Garden. (The arboretum at Benmore Botanic Garden, formerly a private garden for the Younger family, is now open to the public. It comprises 60 hectares (150 acres) and features some of the tallest trees in Britain, including the avenue of Giant Redwoods (Sequoia), some of which are over 37 metres (120 ft) high.

Dunoon is on the west coast of the upper Firth of Clyde, and on the east coast of the claw-shaped Cowal peninsula.

Much of the Cowal peninsula is covered with forest, particularly in the northern stretches and to the west and south with small patches in the south-east and east. To the north and north-west is the Argyll Forest Park that was established in 1935.

As with the rest of the British Isles, Dunoon has a maritime climate with cool summers and mild winters. It is an exceptionally wet part of the country, particularly so for a place near sea-level, with annual average rainfall totals nearing 2,400 mm (94 in).

Recorded temperature extremes since 1960 range from 29.6 °C (85.3 °F) during July 1983 to as low as −13.9 °C (7.0 °F) during January 1982.
