Sheikhpura district is one of the thirty-eight districts in Bihar, India and a part of the Munger division with Sheikhpura as its administrative headquarters. Established on 31 July 1994 from the Munger district due to political efforts by Rajo Singh, it was the least populous district in Bihar as of the 2011 census. Shri Krishna Sinha, the first chief minister of Bihar, was born in Maur village, which is now situated in Barbigha block of this district.

It is believed that during the Mahabharata era, a demoness named Hiḍimbā lived in the hillocks of Sheikhpura's eastern stretch. She married Bhima, one of the Pandava brothers, and they had a heroic son named Gandwa. The hill was later named Girihinda after Hidimba where Giri means a hill in Sanskrit, and the village of Girihinda still exists today.

Sheikhpura also served as a significant administrative center during the Pallava reign. It is also believed that the Afghan ruler Sher Shah Suri had the notable Dal Kuan (well) constructed there.

During the Mughal period, Sheikhpura was designated as a Thana. Under British rule, it became a Big Kotwali, and after independence, it was recognized as a Block. On 14 April 1983, Sheikhpura was established as a Subdivision. It was split from the Munger district into a separate district with headquarters in Sheikhpura on 31 July 1994 due to political efforts of Rajo Singh.

The Sheikhpura district occupies an area of 689 square kilometres (266 sq mi), comparatively equivalent to the Solomon Islands' Kolombangara.
