HMS Oswald was an Odin-class submarine built for the Royal Navy during the 1920s.

She was laid down by Vickers-Armstrongs at Barrow-in-Furness on 30 May 1927, launched on 19 June 1928 and commissioned on 1 May 1929.^[1]

Oswald left Alexandria, Egypt, for a patrol east of Sicily on 19 July 1940. On 30 July, she spotted a convoy of several merchant ships. Her attack on the convoy was not successful and she was spotted by the convoy's escorting destroyers. Subsequently, on 1 August Oswald was rammed and sunk by the Italian destroyer Ugolino Vivaldi while on patrol south of Calabria; 52 crewmen were rescued by Italian warships and 3 were lost.^[2][3]
