Andrew Trần Dũng-Lạc (Vietnamese: Anrê Trần An Dũng Lạc , pronounced as /vi/), French: André Dũng-Lạc; 1795 – 21 December 1839) was a Vietnamese Roman Catholic priest. He was executed by beheading during the reign of Minh Mạng. He is a saint and martyr of the Catholic Church.
He was born Trần An Dũng in Vietnam in 1795. He took the name Andrew at his baptism (Anrê Dũng) and was ordained a priest on 15 March 1823.[2] During persecution, Andrew Dũng changed his name to Lạc to avoid capture, and thus he is memorialised as Andrew Dũng-Lạc (Anrê Dũng Lạc).[3] His memorial is 24 November; this memorial celebrates all of the Vietnamese Martyrs of the 17th, 18th, and 19th centuries (1625–1886).
