Luke Kirby was a 16th-century English Catholic priest who was martyred for his faith. Born in Richmond, North Yorkshire, he later converted to Catholicism while studying at Louvain. After his ordination in Cambrai in 1577, he moved to Rome, where he took an oath at the English College and encountered the informer Anthony Munday. He eventually returned to England alongside Edmund Campion, but his mission led to his arrest at Dover in 1580 and subsequent imprisonment.
