Nhà thờ Cửa Bắc (Cửa Bắc Church) is a Roman Catholic church in Hanoi, Vietnam. Originally named as Church of Martyrs (French: église des Martyrs), the church was built in 1932 by the French administration of Indochina as a part of the Hanoi's urban plan supervised by Ernest Hébrard. Today, Cua Bac Church is one of the three major churches of Hanoi, together with Ham Long Church and Saint Joseph Cathedral. In November, 2006, the Cua Bac Catholic Church became the venue of joint worship service of the Vietnamese Catholics and Protestants with participation of the United States President George W. Bush, who was on an official visit to Vietnam.
