The St Mary Matfelon church, popularly known as St Mary's, Whitechapel, was a Church of England parish church on Whitechapel Road, Whitechapel, London. The church's earliest known rector was Hugh de Fulbourne in 1329, and in the medieval period the church was covered in a lime whitewash, which gave the church and surrounding area its common name. Around 1338, it became called, for unknown reasons, St Mary Matfelon. Last rebuilt in the 19th century, the church was severely damaged during the Blitz, and its location and graveyard is now a public garden on the south side of the road.
