Dimapur (/diməˈpʊər/) is the largest city and municipality in the Indian state of Nagaland. As of 2024 , the municipality had a population of 172,000. The city is the main gateway and commercial centre of Nagaland. Located near the border with Assam along the banks of the Dhansiri River. Its main railway station is the second busiest station in Northeast India.

Many historians explain the name 'Dimapur' as the city of the Dimasa people. The compound word is derived from the Dimasa Kachari words: di (water), ma (big), and pur (settlement).

In the Ahom Buranjis, Dimapur is referred to sometimes as Che-din-chi-pen (town-earth-burn-make) meaning "Brick-town" and its rulers as khun timisa (distorted word for Dimasa).

Situated on the banks of the Dhansiri (originally known as Dong-siri meaning a ravine of peaceful habitation), Dimapur was described as the 'Brick City' by the European scholars and by the Ahoms.

According to local legend, Dimapur is said to have been named after the Mahabharatha character Hidimba. It was first called "Hidimbapur" (Pronounced as Hirhimbapur), which translates to "the city of Hidimba." Later, it changed to Dimbapur, and then to Dimapur. Another legend says that the place is related to Hidimbi, the sister of Hidimba who later married the Pandava prince Bhima and gave birth to Ghatotkacha.

During Arjuna's exile, he married Chitrangada, a princess of Manipur. It is believed that the Kachari kings trace their lineage to Ghatotkacha, Bhima's son. After Ghatotkacha's death in the Kurukshetra battle, his son Sasempha took the throne.

In the 13th century, the city was the capital of the Dimasa Kingdom. In the heart of the city there is an old relic of the Dimasa Kingdom which speaks about the once prosperous era.

The city of Dimapur is said to have been founded by a Kachari king Mahamanipha (1330-1370) and it remained as the capital of the Kacharis until it was captured by the Ahom ruler Suhungmung in 1526 A.D.

It appears that Chinese Ming dynasty had political contacts with the Dimasa and other neighbouring kingdoms between 1406 and 1439. The Ming dynasty canonised the Dimasa kingdom as a tusi in 1406. A Pacification superintendency was established in the Dimasa kingdom and Lawangpa was appointed as the Di-ma-sa Pacification Superintendent. The Ming court sent Zhou Rang, a Supervising Secretary to bestow Imperial orders, patent, seals, paper money, silks etc. to the kingdom and in return, the chieftain of Dimasa sent horses and local products as a sign of tribute. In 1425, paper money, ramie-silks, silk gauzes and thin silk were conferred to Mazhiasa who was sent to the Ming court by Diedaomangpa, the acting head of Di-ma-sa Pacification Superintendency.

It is speculated that Dimasa kingdom is referred to as Timmasala in the Yan-anng-myin pagoda inscription of Burma in 1400 A.D. In this inscription by Minkhaung I, the kingdom of Ava is said to extend on the east to Shan Pyi, northwest to Timmasala, west to Kula Pyi, and south to Talaing Pyi.

In a 1442 inscription from Pagan of Burma mentions Timmasala (Hill Kacharis) to be one of the 21 principalities under Mong Mao ruler Thonganbwa (1413–1445/6), who was later captured by the Governor of Taungdwin and presented to King Narapati I of Ava.

The ruins of Dimasa Kingdom in Dimapur include a brick wall of the length of nearly 2 miles and 2 tanks about 300 yards square, are indicative of a city of considerable size.

During World War II, Dimapur was the centre of action between British India and Imperial Japan. It was the staging post for the Allied offensive. The Japanese could reach Kohima where a siege was laid. Allied reinforcement came through Dimapur by rail and road for the push against the Japanese. An airport at Dimapur was also in use for supplies to the allied forces in Burma. The Battle of Kohima about 77 km from Dimapur is considered the turning point for the Japanese retreat from Southeast Asia.

In 1918, Dimapur was leased to then Naga Hills District (Now Nagaland) by then erstwhile Assam Province of British of India for 30 years for construction of Railways lines (unclear from which district). In 1963, it was again leased to now state of Nagaland for 99 years. There is controversy surrounding this claim, as both state governments have not come forward to comment on the matter.

On 2 October 2004, two powerful bombs were set off—one at the Dimapur Railway Station and the other at the Hong Kong Market killing 30 and injuring over 100 others.
