HMS A2 was an early Royal Navy submarine.

She was a member of the first British A-class of submarines, although slightly bigger than the lead ship, HMS A1. Like all boats in her class, she was built at Vickers, Barrow-in-Furness. She was launched on April 15, 1903. She flooded after running aground in Bomb Ketch Lake, Portsmouth in January 1920 and was sold for scrap.
