HMS R11 was a British R class submarine built by Cammell Laird at Birkenhead. She was laid down on 1 December 1917 and launched on 16 March 1918. R11 was commissioned on 8 August 1919. She came too late to see any combat in World War I, like most of the other R class submarines. R11 was sold on 21 February 1923 to J Smith.
The ship's bell of R11 is held by the Royal Navy Submarine Museum at Gosport.
