MV Doña Paz was a Japanese-built and Philippine-registered passenger ferry that sank after she collided with the oil tanker Vector on December 20, 1987. Built by Onomichi Dockyard Co., Ltd. of Hiroshima, Japan, the ship was launched on April 25, 1963 as the Himeyuri Maru with a passenger capacity of 608. In October 1975, the Himeyuri Maru was bought by Sulpicio Lines and renamed the Don Sulpicio. After a fire aboard in June 1979, the ship was refurbished and renamed Doña Paz.
