The MV Krait /ˈkraɪt/ is a wooden-hulled vessel famous for its use during World War II by the Z Special Unit (Z Force) of Australia during the raid against Japanese ships anchored in Singapore Harbour.

In September 1943, Krait transported members of Z Special Unit to Singapore, where they successfully raided the city's harbour, sinking seven ships, in what became known as Operation Jaywick.

Krait was later used as transport for intelligence-gathering missions to islands in the area, including Buru, Aru, Ceram, Banda, and Saparua.

She was then sailed to Labuan, where she was sold and handed over to the British Borneo Company and where Able Seaman Robert Harry Easom of Perth kept its ensign as a souvenir.
