John Henry Okullu (1929, Ramba Village, Asembo Central Location, Siaya District, Nyanza Province – 1999) was a Kenyan Anglican bishop and theologian.
Okullu was a bishop in the Anglican Church of Kenya known for his outspoken criticism of the Kenyan government.
He was consecrated as the first black provost of the Nairobi All Saints Cathedral in 1971 and Bishop of Maseno South Diocese where he served until his retirement in 1994.
His first book was "Church and Politics in East Africa", published in 1974, which was an early call for pluralistic democracy.
