HMS F1 was a British F class submarine of the Royal Navy. She was built at Chatham Dockyard, laid down 1 December 1913 and launched 31 March 1915. F1 was broken up in Portsmouth in 1920. The F class submarine was built for the Royal Navy as a coastal submarine based on the doubled hulled V class submarine (World War I) with very few minor improvements. The only important improvement was the addition of a stern torpedo tube. The F class were ordered as a successor to the E class submarine, but only three were built out of the ten ordered.
