Richard Challoner (1691–1781) was an English Roman Catholic bishop, scholar, and writer. Born in London to Protestant parents, he later converted to Catholicism and was ordained a priest in 1716. He became Vicar Apostolic of the London District in 1758, ministering to Catholics during a time of penal laws and persecution. Challoner is best known for revising the Douay–Rheims Bible, producing the standard English Catholic edition for over 200 years. He also authored devotional works, catechisms, and historical writings that sustained English Catholic faith and identity through difficult times.
