HMS Tiptoe (pennant number P332) 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 in with a coastal streamer 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
