William O'Bryan (1778–1868) was a significant figure in the history of Methodism. He is best known for founding the Bible Christian Church in 1815, a dissident sect of Wesleyan Methodists. His initiative was primarily aimed at promoting effective biblical education and adapting Methodism to better meet the spiritual needs of rural populations in Britain. Born on Gunwen farm in Luxulyan, Cornwall, O'Bryan was an Evangelical Protestant preoccupied with spreading the Christian faith among the unchurched.
