Thomas Belchiam (1508–1537) was an English Franciscan who died in Newgate Prison in the reign of Henry VIII. He is a Catholic martyr, declared venerable by Pope Leo XIII. The year of death is in question: the Victoria County History for Kent puts the events in 1534. It references Thomas Bourchier's Historia Ecclesiastica de Martyrio Fratrum..., "though the writer assigns them to 1537". Dom Bede Camm, O.S.B., places Belchiam's date of death as 3 August 1537. Notes and Queries lists him as dying in 1538.
