Dehradun (/ˌdɛrəˈduːn/, ISO: Dēharādūna), also known as Dehra Doon, is the winter capital and the most populous city of the Indian state of Uttarakhand. It is the administrative headquarters of the eponymous district and is governed by the Dehradun Municipal Corporation, with the Uttarakhand Legislative Assembly holding its winter sessions in the city as its winter capital. Part of the Garhwal region, and housing the headquarters of its Divisional Commissioner, Dehradun is one of the "Counter Magnets" of the National Capital Region (NCR) being developed as an alternative centre of growth to help ease the migration and population explosion in the Delhi metropolitan area and to establish a smart city in the Himalayas.

Dehradun is located in the Doon Valley on the foothills of the Himalayas nestled between Song River, a tributary of Ganges on the east and the Asan River, a tributary of Yamuna on the west. The city is noted for its picturesque landscape and provides a gateway to the surrounding region.

Dehradun is a notable academic and research hub and is home to the Indian Military Academy, Forest Research Institute, Indira Gandhi National Forest Academy, the Doon School, Welham Boys School, Welham Girls School, Brightlands School, Rashtriya Indian Military College, Uttarakhand Ayurveda University, Wadia Institute of Himalayan Geology and the Indian Institute of Remote Sensing. It is the headquarters of the Surveyor-General of India. According to the combined survey based on health, infrastructure, economy, education, and crime, conducted by Dainik Jagran and KPMG, Dehradun is one of India's safest cities. Dehradun is also known for its Basmati rice and bakery products.

Also known as the "Abode of Drona", Dehradun has been an important centre for Garhwal rulers, which was first captured by Gorkha Kings, in January 1804, and then by the British. For its strategic value, in addition to the location of its principal service academy, the Indian Armed Forces maintain a considerable presence in Dehradun, at the Garhi Cantonment and Naval Station. The Uttarakhand Police is the primary law enforcement agency in the city.

It is well connected and in proximity to Himalayan tourist destinations such as Mussoorie, Dhanaulti, Chakrata, New Tehri, Uttarkashi, Harsil, Chopta-Tungnath, Auli, and summer and winter hiking destinations like the Valley of Flowers at Dodital, Dayara Bugyal, Kedarkantha, Har Ki Dun and Hemkunt Sahib for camping and Himalayan panoramic views. The Hindu holy cities of Haridwar and Rishikesh, along with the Himalayan pilgrimage circuit of Chota Char Dham, viz. Yamunotri, Gangotri, Kedarnath and Badrinath, are also primarily accessed via Dehradun, the closest major city.

Dehradun is made up of two words "dehra" + "dun." "dehra" is a Hindi word with the meaning of temple, whose etymology is: "dev" + "ghar", from Prakrit "devahara." "dūn" (or Hindi दून derives from the Sanskrit droṇī (or द्रोणि) and means "a tract of country lying at the foot of hills; a valley"

The town was established when Baba Ram Rai, the son of the seventh Sikh Guru, Guru Har Rai built a gurudwara or temple in the area in the 17th century. Ram Rai was sent by his father as an emissary to the Mughal emperor Aurangzeb in Delhi. Aurangzeb objected to a verse in the Sikh scripture (Asa ki Var) that stated, "the clay from a Musalman(Muslim)'s grave is kneaded into potter's lump", considering it an insult to Islam. Baba Ram Rai explained that the text was miscopied and modified it, substituting "Musalman" with "Beiman" (faithless, evil) which Aurangzeb approved. This led Guru Har Rai to bar his son from his presence, and name his younger son as his successor. Aurangzeb responded by granting Baba Ram Rai a jagir (land grant) in Garhwal region (Uttarakhand). The town later came to be known as Dehradun, after Dehra referring to Baba Ram Rai's shrine. Many followers of Ram Rai, called Ramraiyas, settled with Ram Rai. During the days of British Raj, the official name of the town was Dehra. In due time the word Dehra was linked to Dun, and thus the city was named Dehradun.

In the Skanda Purana, Dun is mentioned as a part of the region called Kedarkhand, the abode of Shiva. According to Hindu mythology, in ancient India during the Mahabharata epic era, Dronacharya, the great teacher of Kauravas and Pandavas, lived here, hence the name of "Dronanagari" (lit. city of Drona).

The history of the city of Uttarakhand, Dehradun (nicknamed "Doon Valley") is linked to the story of Ramayana and Mahabharata. It is believed that after the battle between Ravana and Rama, Rama and his brother Lakshmana visited this site. Also, known as 'Dronanagari' on the name of Dronacharya, legendary Royal guru to the Kauravas and Pandavas in the epic Mahabharata, is believed to have been born and resided in Dehradun. Evidence such as ancient temples and idols have been found in the areas surrounding Dehradun which have been linked to the mythology of Ramayana and Mahabharata. These relics and ruins are believed to be around 2000 years old. Furthermore, the location, the local traditions and the literature reflect this region's links with the events of Mahabharata and Ramayana. Even after the battle of Mahabharata, the Pandavas had an influence on this region as the rulers of Hastinapura with the descendants of Subahu ruled the region as subsidiaries. Likewise, Rishikesh is mentioned in the pages of history when Vishnu answered the prayers of the saints, slaughtered the demons and handed the land to the saints. The adjoining place called Chakrata has its historical impression during the time of Mahabharata.

In the seventh century, this area was known as Sudhanagara and was described by the Chinese traveller Huen Tsang. Sudhanagara later came to be recognised as Kalsi. Edicts of Ashoka have been found in the region along the banks of the river Yamuna in Kalsi indicating the wealth and importance of the region in ancient India. In the neighbouring region of Haripur, ruins were discovered from the time of King Rasala which also reflect the region's prosperity. It was under control of Garhwal for many centuries.

Fateh Shah, a Garhwal king, donated three villages in Dehradun to Sikh guru Ram Rai. Before the name of Dehradun was used, the place is shown on old maps as Gurudwara (a map by Webb, 1808) or Gurudwara (a map by Gerard, 1818). Gerard's map names the place as "Dehra or Gurudwara". Surrounding this original Sikh temple were many small villages that are now the names of parts of the modern city.

Dehradun itself derives its name from the historical fact that Baba Ram Rai, the eldest son of the Seventh Sikh Guru Har Rai, set up his "Dera" (camp) in "dun" (valley) in 1676. This 'Dera Dun' later on became Dehradun.

The Mughal Emperor Aurangzeb was highly impressed by the miraculous powers of charismatic Ram Rai. He asked the contemporary Maharaja of Garhwal, Fateh Shah to extend all possible help to Ram Rai. Initially, a Gurudwara (temple) was built in Dhamawala. The construction of the present building, Guru Ram Rai Darbar Sahib, was completed in 1707. There are portraits of gods, goddesses, saints, sages and religious stories on the walls. There are pictures of flowers and leaves, animals and birds, trees, similar faces with pointed noses and big eyes on the arches which are the symbol of the colour scheme of Kangra-Guler art and Mughal art. High minarets and round pinnacles are the models of Muslim architecture. The huge pond in the front measuring 230 by 80 feet (70 m × 24 m) had dried up for want of water over the years. People had been dumping rubbish; it has been renovated and revived.

Dehradun was invaded by Mahmud of Ghazni during his campaigns into India followed by Timur in 1368, Rohilla chief Najib ad-Dawlah in 1757 and Ghulam Qadir in 1785. In 1804 battles of Khurbura at Dehradun fought between Garhwal king Pradyuman shah and Gorakhali forces led by General Amar Singh thapa.in which king Pradyuman shah died then this area came under control of Gorakha. In 1806 the Nepalese warlord Kaji Amar Singh Thapa under the central leadership of Prime Minister Mukhtiyar Bhimsen Thapa united many of the Indian territories that now fell under places such as Almora, Pathankot, Kumaon, Garhwal, Sirmur, Shimla, Kangra and Dehradun.

On the western front Garhwal and parts of Himachal Pradesh up to Punjab and on the eastern front the state of Sikkim up to Darjeeling became parts of Nepal for a brief period until the British East India Company went to war from 1814 to 1816. The war ended with the signing of the Treaty of Sugowli where almost a third was ceded to British East India company. The British got Dehradun in 1816 and colonised Landour and Mussoorie in 1827–1828.

Jawaharlal Nehru, India's first prime minister, was quite fond of the city and often visited. He spent his last few days here before passing away in Delhi in 1964. Another leader from the independence movement, Rash Behari Bose, who was one of the key organisers of the Ghadar conspiracy and, later, the Indian National Army was based in Dehradun in his early days before he was forced to move to Japan in 1915 to continue the freedom struggle.

Post-independence Dehradun and other parts of Garhwal and Kumaon were merged with United Provinces which was later renamed the state of Uttar Pradesh. In 2000, Uttarakhand state (earlier called Uttaranchal) was created from the northwestern districts of Uttar Pradesh under the Uttar Pradesh Reorganisation Act, 2000. Dehradun was made its interim capital.

Dehradun's Afghan connection dated back to the First Anglo-Afghan War, after which the Afghan Emir Dost Mohammad Khan was exiled by the British to Dehradun. He stayed in Mussoorie for over 6 years. The Balahissar ward under the Mussoorie municipality has been named after the palace of Dost Mohammad. The famous Dehradooni Basmati was brought along by him from Kunar Province in Afghanistan and it continues to be counted as a delicacy of the valley. According to Dehradun historian and heritage activist Lokesh Ohri, "Dost Mohammad Khan was fond of pulao and missed it during his exile. He brought Basmati to the Doon valley and is credited with improving its genetic variety. His grandson Yaqub Khan gave Basmati seeds to a Paltan Bazaar trader and asked him to cultivate them in Dehradun. Surprisingly, the Doon valley's weather suited the rice and it turned out even better than the variety in Afghanistan."

Forty years later, after the Second Anglo-Afghan War, his grandson, Mohammad Yaqub Khan, was sent to exile to India in 1879. Just like his grandfather, he chose Doon valley as his abode. Yakoob became the first Afghan to formally settle in Dehradun. The present Mangla Devi Inter College was once the Kabul Palace where Yakoob spent a few years of his life. The extended family and servants of the King were also relocated to Dehradun.

The Afghan royal family maintained a presence in Dehra Dun. It was the birthplace of the second to last King of Afghanistan, Mohammed Nadir Shah. Two quaint palaces – the Kabul Palace in Dehradun and Bala Hissar Palace in Mussoorie – stand testimony to this connection with Afghanistan. They were built by these Afghan rulers in exile in India in the early part of the 20th Century and are palaces are a miniature replica of the palatial structures owned by the kings in Afghanistan. The Bala Hissar Palace has now been turned into Mussoorie's Wynberg Allen School. Doon-based heritage enthusiast Ghanshyam told the Times of India, "The police station at Karanpur used to be the royal guard room of Yakoob way back in 1879. The electrical office located at the Survey Chowk was the royal servants quarter."

Today the descendants of the former royalty, Yakub Khan and his grandson Sardar Azim Khan's family have integrated with the mainstream of Dehradun life. The Doon connection was revived when Zahir Shah, the last king of Afghanistan while undergoing treatment in New Delhi during the last years of his life expressed a desire to meet his Doon cousins but the meeting could not take place as the family members were away. Ashraf Ghani, former President of Afghanistan has mentioned that his grandmother grew up in Dehra Dun. "I speak of Tagore because I was raised on Tagore by my grandmother who lived in Dehradun...," Dr Ghani said while talking about India's vision and the remarkable transformation. Dehradun is also being selected to be the second "home" ground of the Afghan cricket team. and Afghan cricket fans recall this "centuries old link" with the town.

The city of Dehradun mainly lies in Doon Valley and is at a varying height from 410 m (1,350 ft) in Clement Town to above 700 m (2,300 ft) at Malsi which is 15 km (9.3 mi) from the city. However, the average elevation is 450 m (1,480 ft) above sea level. Malsi is the starting point of Lesser Himalayan Range that extends to Mussoorie and beyond. Jaunsar-Bawar hills in Dehradun district rises to 3,700 m (12,100 ft) above sea level. The hilly region of Mussoorie goes up to a height of 1,870–2,017 m (6,135–6,617 ft) above sea level. Its geomorphological and meteorological characteristics make it prone to a number of natural hazards. Beside earthquakes, the region is frequently devastated by landslides, cloudbursts, flash-floods, cold waves and hailstorms.

The Doon valley contains the settlements including Raiwala, Rishikesh, Doiwala, Harrawala, Dehradun, Herbertpur, Vikasnagar, Sahaspur, Selaqui, Subhash Nagar and Clement Town. The district houses Rajaji National Park which is home to elephants, Benog Wildlife Sanctuary at Mussoorie & Asan Conservation Reserve (Asan Barrage). The Doon Valley has the Terai and Bhabar forests within it as well as the Shivalik hills and Lesser Himalayan Range containing hill stations such as Mussoorie and Chakrata. The district is bordered by the Himalayas in the north, Rajaji Range of the Sivalik Hills to the south, the river Ganges to the east, and the Yamuna river to the west. Towns in the foothills of the mountain ranges include Sahastradhara, Lakhamandal, Gautam Kund, Chandrabani, Kalsi and Dakpathar.

This district is divided into two major parts: the main city Dehradun surrounded by Shivalik and the Jaunsar-Bawar, which is in the foothills of Himalayas. In the north and northwest it borders on the district of Uttarkashi and Tehri Garhwal, in the east and southeast by Pauri Garhwal and Ganges river, in the west, it is bordered by Shimla and Sirmaur districts of Himachal Pradesh, Yamunanagar district of Haryana and the Tons and Yamuna rivers. To the south are Haridwar and Uttar Pradesh's Saharanpur district. It is between latitudes 30°01' N and 31°2'N and longitudes 77°34' E and 78°18'E. This district consists of six tehsils – Dehradun, Chakrata, Vikasnagar, Kalsi, Tiuni and Rishikesh – six community development blocks – Vis, Chakrata, Kalsi, Vikasnagar, Sahaspur, Rajpur and Doiwala – 17 towns and 764 villages. Out of these 746 villages are inhabited; 18 are uninhabited.

There was once an extensive canal network in the city, which irrigated many surrounding villages and produced a cooler microclimate in the region. The earliest canal, Rajpur canal, was laid in the 17th century but after Dehradun became the state capital in 2000, most of the heritage canals were covered or demolished to widen the city roads. Environmental groups have campaigned for the revival of the network, citing its benefit for the city's ecology, aesthetics, microclimate and built environment.

The climate of Dehradun is humid subtropical (Cwa). The city is in Doon Valley and temperature variations due to difference in elevation are considerable. In the hilly regions, the summer is pleasant. But in the Doon, the heat is in rare cases, intense and summer temperatures can reach up to 40 °C (104 °F) for a few days and hot winds (called Loo) blows over North India. Winter temperature drops below freezing point and is usually between 6 and 20 °C (43 and 68 °F). Although the temperature in Dehradun can reach below freezing during severe cold snaps, this is not common. The area receives an average annual rainfall of 2,073.3 mm (81.63 in).
