The Diocese of Lucknow is a diocese of the Church of North India, headquartered in the city of Prayagraj. The jurisdiction of the diocese mainly covers the Eastern side of Uttar Pradesh.^[1]

The diocese of Lucknow was established in 1893 by carving it out from the Diocese of Calcutta. The diocese was given the name of Lucknow although the mother Cathedral, All Saints Cathedral and diocesan headquarters stayed in Prayagraj. It was because Prayagraj was situated within the legally defined territories of the diocese of Calcutta.

^[2] It is the biggest Diocese in Uttar Pradesh and one of the oldest dioceses in north India.
