'''HMS ''K15''''' was a [[British K class submarine|K class]] [[submarine]] built by [[Scotts Shipbuilding and Engineering Company|Scotts]], [[Greenock]]. She was laid down on 19 April 1916 and was commissioned on 30 April 1918.

''K15'' sank due to an accident, when moored alongside the light cruiser {{HMS|Canterbury|1915|2}} at [[Portsmouth]] Harbour on 25 June 1921. She was then salved in July 1921. ''K15'' was sold in August 1924 in Upnor.
