Uttar Dinajpur (Bengali pronunciation: [ut̪ːor dinadʒpur]), also known as North Dinajpur, is a district of the Indian state of West Bengal. Created on 1 April 1992 by the division of the erstwhile West Dinajpur district, it comprises two subdivisions: Raiganj and Islampur.

Undivided Dinajpur district was part of the Pundra and Gauda Kingdom of ancient Bengal. The whole of Pundra was part of the Mauryan empire, and Jainism was spread in the region in the fourth century BCE. Their capital was at Pundrabardhan (now in Bangladesh), and two other ancient towns were Gourpur and Kotibarsha, now called Bangarh. Later multiple inscriptions show how the Guptas also controlled Pundra. After the reign of Gauda Kingdom, the district was then ruled by Pala Empire from 750 CE. The Senas overthrew the Palas in 1143. In 1204, Bakhtiyar Khilji defeated the Senas and had Bangarh as its capital. After his murder, it was controlled by various governors sent by the Delhi Sultan from Gauda. In 1586, Mughal Emperor Akbar conquered Bengal and Dinajpur was controlled by the sarkars of Tajpur and Panjara. In 1765, it fell under the rule of the East India Company and was ruled from Murshidabad. In the later part of the 18th century, the district was home to the Sanyasi-Fakir rebellion until the early 19th century. The district remained relatively peaceful all through the rest of the 1800s. In 1905, the people of Dinajpur district protested against the Partition of Bengal. They participated in the Freedom struggle by refusing to pay tax, doing hartals, and launching agitations. In 1947, Dinajpur district was split between India and Pakistan with West Dinajpur remaining with India. In 1992, West Dinajpur district was bifurcated to form Uttar Dinajpur and Dakshin Dinajpur districts.
