Raebareli District is a district of Uttar Pradesh state in northern India. The town of Raebareli is the district headquarters. The district is part of Lucknow Division.

Raebareli has always been a politically active district of Uttar Pradesh finding itself at the center of The Emergency. Raj Narain who opposed policies and practices of Indira Gandhi, contested against the Prime Minister in 1971 Lok Sabha elections from Rai Bareli, as a Janta Party candidate. Although he suffered a defeat, but he accused Indira Gandhi of corrupt electoral practices and filed an election petition against her. The Allahabad High Court on 12 June 1975 upheld the accusations and set aside the election of Indira Gandhi and also disqualified her to contest Lok Sabha election for next 6 years, which led to the imposition of Emergency in India.
