Chandigarh (/ˌtʃʌndɪˈɡɑːr/) is a city and union territory in northern India, serving as the shared capital of the states of Punjab and Haryana. Situated near the foothills of the Himalayas, it borders Haryana to the east and Punjab in the remaining directions. Chandigarh constitutes the bulk of the Chandigarh Capital Region or Greater Chandigarh, which also includes the adjacent satellite cities of Panchkula in Haryana and Mohali in Punjab. It is located 260 km (162 miles) north of New Delhi and 229 km (143 miles) southeast of Amritsar.

Chandigarh is one of the earliest planned cities in post independence India and is internationally known for its architecture and urban design. The master plan of the city was prepared by Swiss-French architect Le Corbusier, which built upon earlier plans created by the Polish architect Maciej Nowicki and the American planner Albert Mayer. Most of the government buildings and housing in the city were designed by a team headed by Le Corbusier, Jane Drew and Maxwell Fry. Chandigarh's Capitol Complex—as part of a global ensemble of Corbusier's buildings—was declared a World Heritage Site by UNESCO at the 40th session of the World Heritage Conference in July 2016.

Chandigarh has grown greatly since its initial construction, and has also driven the development of Mohali and Panchkula; the "tri-city" metropolitan area has a combined population of over 1,611,770. The city has one of the highest per capita incomes in the country. The union territory has one of the highest Human Development Index among Indian states and territories. In 2015, a survey by LG Electronics ranked it as the happiest city in India on the happiness index. In 2015, an article published by BBC named Chandigarh one of the few master-planned cities in the world to have succeeded in terms of combining monumental architecture, cultural growth, and modernisation.

The name Chandigarh is a compound of Chandi and Garh. Chandi refers to the Hindu goddess Chandi and Garh means fortress. The name is derived from Chandi Mandir, an ancient temple devoted to Chandi near the city in Panchkula District.

The motif or sobriquet of "The City of Beauty" was derived from the City Beautiful movement, which was a popular philosophy in North American urban planning during the 1890s and 1900s. Architect Albert Mayer, the initial planner of Chandigarh, lamented the American rejection of City Beautiful concepts and declared, "We want to create a beautiful city..." The phrase was used as a logo in official publications in the 1970s and is now how the city describes itself.

As part of the partition of India in 1947, the former Indian province of Punjab was divided into two parts, the mostly Hindu and Sikh East Punjab in India, and the mostly Muslim West Punjab in Pakistan. The capital of undivided Punjab, Lahore, had become part of Pakistan after the partition. Instead of shifting the capital to an already existing and established city, Jawaharlal Nehru, the first Prime Minister of India, envisioned an altogether new and modern city to be built to serve as the capital of Punjab. Partap Singh Kairon, then the Chief Minister of East Punjab, and Edward Nirmal Mangat Rai, then the Chief Secretary of East Punjab, were instrumental in creating Chandigarh as the capital of the state. In 1949, the American planner and architect Albert Mayer was commissioned to design a new city to be called "Chandigarh". The government carved out Chandigarh from about fifty Puadhi-speaking villages in the then-state of East Punjab, India. Shimla was the temporary capital of the state until Chandigarh was completed.

Albert Mayer developed a superblock-based city interspersed with green spaces, with an emphasis on cellular neighbourhoods and traffic segregation. His site plan took advantage of natural land characteristics; the land's gentle grade promoted proper drainage. Mayer stopped his work on the city after his architect-partner Matthew Nowicki died in a plane crash in 1950. Government officials recruited Le Corbusier to succeed Mayer and Nowicki, who utilised many elements of Mayer's original plan without attributing them to him. Le Corbusier designed many administration buildings, including the High Court, the Palace of Assembly, and the Secretariat Building. Le Corbusier also designed the general layout of the city, dividing it into sectors. Chandigarh hosts the largest of Le Corbusier's many Open Hand sculptures, standing 26 metres high. The Open Hand (La Main Ouverte) is a recurring motif in Le Corbusier's architecture, a sign for him of "peace and reconciliation. It is open to give and open to receive." It represents what Le Corbusier called the "Second Machine Age". Two of the six monuments planned in the Capitol Complex which has the High Court, the Assembly, and the Secretariat, remain incomplete. These include Geometric Hill and Martyrs Memorial. Drawings were made, and they were begun in 1956, but they were never completed.

The capital city was officially shifted from Shimla to Chandigarh on 21 September 1953, though Chandigarh was formally inaugurated by India's first president, Rajendra Prasad on 7 October 1953.

During excavations at the time of the building of the city, some Indus Valley artefacts were discovered, suggesting that the area that is today Chandigarh was home to some settlements of the Indus Valley civilisation. On 1 November 1966, after a long-drawn movement demanding the formation of a Punjabi state, the former state of Punjab was split in two. The western and northern mostly Punjabi-speaking portion became the present-day state of Punjab, while the eastern and southern Hindi- and Haryanvi-speaking areas became Haryana. Chandigarh ended up being located on the border of the two states, and both of them moved to incorporate the city into their respective territories. However, the city of Chandigarh was controlled directly by the central government and was to serve as the shared capital of the two states until a resolution could be reached.

It has been noted by industrialists that large real-estate projects have stagnated since the creation of Chandigarh in Punjab and Haryana as an economic rival city would be perceived as a city that could be used as capital instead of Chandigarh and hence relinquishing the state of rights over Chandigarh.[1]

Present-day Chandigarh was also the site of a short-lived late 18th-century principality, with a small fort at Mani Majra. Many villages that predate the city are still inhabited within the modern blocks of some sectors, including Burail and Attawa, while several other such villages lie on the margins of the city.

The maximum amount of rain received by the city of Chandigarh during the monsoon season is 195.5 millimetres or 7.70 inches in a single day.
• Winter: Winters (November-end to February-end) are mild but can get chilly during peak winter weeks. Average temperatures in the winter generally fluctuate between a maximum of 5 to 14 °C or 41.0 to 57.2 °F and a minimum of −1 to 5 °C or 30.2 to 41.0 °F.

Chandigarh has been ranked 27th best “National Clean Air City” (under Category 1 >10L Population cities) in India.

Most of Chandigarh is covered by dense banyan and eucalyptus plantations. Ashoka, cassia, mulberry and other trees flourish in the forested ecosystem. The city is surrounded by forests that sustain many animal and plant species. Deer, sambars, barking deer, parrots, woodpeckers, and peacocks inhabit the protected forests. Sukhna Lake hosts a variety of ducks and geese and attracts migratory birds from parts of Siberia and Japan in the winter season. The Parrot Bird Sanctuary Chandigarh provides a home to a large number of parrots. Sukhna Wildlife Sanctuary was declared a wildlife sanctuary in 1998.

The Department of Forest & Wildlife Chandigarh Administration is the nodal department for this purpose and has published a detailed booklet about it. The trees in the city that are a hundred or more years old have been given heritage status.

Sukhna Lake, a 3 km artificial rain-fed lake in Sector 1, was created in 1958 by damming the Sukhna Choe, a seasonal stream coming down from the Shivalik Hills.

Article 239 of the Constitution of India provides for the administration of the Union Territories by the President through an administrator. Since 1984 the Governor of Punjab has served concurrently as the administrator of Chandigarh. Gulab Chand Kataria has been the administrator of the union territory since 27 July 2024.

Chandigarh, as a union territory, is not entitled to a state-level election: thus State Assembly elections are not held and it is directly controlled by the central government. One seat for Chandigarh is allocated in the Lok Sabha elections held every five years.

Manish Tewari (INC) is the Member of Parliament elected in 2024 from the Chandigarh Lok Sabha constituency.

The city is governed by a civic administration or local government headed by Municipal Commissioner Anindita Mitra and Mayor Sarbjit Kaur. The city comprises 35 wards represented by 35 elected councillors, and also nominates 9 councillors.

On 27 March 2022, Union Home Minister Amit Shah announced that the Chandigarh employees who were working under the Punjab service rules until 2022, would be working under the central civil services rules from 1 April 2022. The move was criticised by political parties such as the AAP, the INC and the Akali Dal.

The prime responsibilities of the civic body Municipal Corporation Chandigarh, are to ensure cleanliness and sanitation in the city, illumination of street lights, maintenance of parks, and sewerage disposal. The city has both brick and pipe sewers laid in four phases. In September 2020, the civic body announced that it would upgrade and renew the 50-year-old sewerage system. The pilot project for the 24x7 water supply is expected to begin in Chandigarh in May 2021, which was initially to start in September 2020 and end in March 2022. On 8 April 2021, the Chandigarh Smart City Ltd (CSCL) board is yet to take the final decision.

In 2021, the BJP-ruled corporation had increased the water tariff by 1.5 to 2.5 times. This created a widespread discontent among the residents.

In 2021, there was an acute shortage of parking spaces. The problem was aggravated by an increase of 17% in parking rates by the Municipal Corporation. The increase in the waste collection charges, water tariff and property tax rates during the last five years 2016 to 2021 were unpopular among the public.

During the COVID-19 pandemic in India, concerns were raised about whether sufficient relief measures had been taken by the local government. The sitting Councillors were accused of not being found to be approachable when the public needed support.

The government is a major employer in Chandigarh, with three governments having their base here, those being the Chandigarh Administration, the Punjab government, and the Haryana government. A significant percentage of Chandigarh's population, therefore, consists of people who are either working for one of these governments or have retired from government service, mainly armed forces. For this reason, Chandigarh is often called a "Pensioner's Paradise". Ordnance Cable Factory of the Ordnance Factories Board has been set up by the Government of India. There are about 15 medium-to-large industries, including two in the public sector. In addition, Chandigarh has over 2,500 units registered under the small-scale sector. The city's important industries are paper manufacturing, basic metals and alloys, and machinery. Other industries in the city are food products, sanitary ware, auto parts, machine tools, pharmaceuticals, and electrical appliances.

The main occupation here is trade and business. However, the Punjab and Haryana High Court, Post Graduate Institute of Medical Education and Research (PGIMER), the availability of an IT Park, and more than a hundred government schools provide other job opportunities to people.

Four major trade promotion organisations have their offices in Chandigarh. These are The Associated Chambers of Commerce & Industry, ASSOCHAM India, Federation of Indian Chambers of Commerce & Industry, (FICCI) the PhD Chamber of Commerce and Industry and the Confederation of Indian Industry (CII) having regional offices in Chandigarh.

Chandigarh IT Park (also known as Rajiv Gandhi Chandigarh Technology Park) is the city's attempt to break into the information technology world. Chandigarh's infrastructure, proximity to Delhi, Haryana, Punjab, and Himachal Pradesh, and the IT talent pool attract IT businesses looking for office space in the area. Major Indian firms and multinational corporations like Quark, Infosys, EVRY, TechMahindra, Airtel, Amadeus IT Group, DLF have set up base in the city and its suburbs.

The work of the Chandigarh Metro was slated to start by 2019. It was opposed by the Member of Parliament from Chandigarh, Kirron Kher. With an estimated cost of around ₹109 billion including 50% funds from the governments of Punjab and Haryana and 25% from Chandigarh and government of India, funds from the Japanese government were proposed to include approximately 56% of the cost. However, the project was turned down owing to its non-feasibility. Kher promised a film city for Chandigarh. After winning the seat, she said that she had difficulty in acquiring land in Chandigarh. Her proposal was accepted by the Chandigarh Administration and the film city is proposed to be set up in Sarangpur, Chandigarh. This has been considered as a source of employment in the future.
