Captain Duncan Herbert Stevens (23 March 1921 – 10 February 1964) was a Royal Australian Navy officer, best remembered for being in command of HMAS Voyager when she collided with HMAS Sydney in 1964, leading to his death. After former Voyager executive officer Peter Cabban alleged that Stevens had been unfit for command, a royal commission was convened in 1967: it found that Stevens was unfit to command for medical reasons, though it only sustained some of Cabban's allegations.
