HMS M3 was built by Armstrong Whitworth, Newcastle Upon Tyne as a British M class submarine for the Royal Navy. She was laid down on the 4 December 1916 and was commissioned in July 1920. She was originally conceived as K20, but renamed prior to launch.

M3's main 12" gun was removed in Chatham in 1927-1928 following the signing of the 1922 Washington Treaty. The upper deck was modified to carry a casing with a conveyor belt to carry and launch over the stern 80 type B mines which was then changed to 100. The mines were laid through a door at the stern. M3 proved to be a successful minelayer and was used in the design of the Porpoise class minelayers.

On the 9th to the 15th May 1926, M3 was used to generate electricity during a general strike for the Royal Victoria and Albert and King George V Docks in London.

M3 was sold on 16 February 1932. She was then scrapped at Newport in April 1932.

HMS Raglan was also known by the name HMS M3 for a short time.
