HMAS Sheean (SSG 77) is the fifth of six Collins-class submarines operated by the Royal Australian Navy (RAN).

Named for Ordinary Seaman Edward Sheean VC—the only submarine of the class to be named for an enlisted sailor—the boat was laid down in 1994 and launched in 1999. Sheean and sister boat Dechaineux were modified during construction as part of the "fast track" program—an attempt to fix the problems affecting the Collins class, and put at least two fully operational submarines in service before the last Oberon-class submarine was decommissioned.
