HMS Tiptoe was a British submarine of the third group of the T class. She was built by Vickers Armstrong, Barrow, and launched on 25 February 1944. She was one of two submarines named by Winston Churchill, and so far has been the only ship of the Royal Navy to be named Tiptoe. In 1955 she was involved in a collision with a coastal steamer whilst in Tromsø harbour. She was involved in escape trials off Malta in 1962, and the commanding officer was reprimanded in 1964 following an incident in the Firth of Clyde where she was run aground, and again in 1965 when she collided with HMS Yarmouth. Although originally named for the ability to sneak up on someone undetected, she maintained several links with ballet, including the Royal Ballet and ballet dancer Moira Shearer. She was scrapped at Portsmouth in 1975, while her anchor is on display in Blyth, Northumberland.

The Royal Navy's T class of diesel-electric submarines was designed in the 1930s to replace the O, P, and R classes. Fifty-three members of the class were built just before and during the Second World War, where they played a major role in the Royal Navy's submarine operations. Four boats in service with the Royal Netherlands Navy were known as the Zwaardvisch class.
