HMS Rifleman was an Acorn-class destroyer built by J. Samuel White & Company, Cowes, completed on 4 November 1910 and sold for breaking up on 9 May 1921.

The British Admiralty ordered 20 Acorn-class destroyers as part of the 1909–1910 shipbuilding programme for the Royal Navy.

[4] She was one of seven destroyers that suffered problems when steaming at full speed off the coast of Ireland during the 1911 Naval Manoeuvres, with serious leaks of water through hull rivets into the ships' oil tanks, requiring that they put into Portland Harbour for repairs.

[7] On the outbreak of the First World War, the 2nd Destroyer Flotilla, including Rifleman joined the newly established Grand Fleet at Scapa Flow.

[10] On 12–13 November 1914, Rifleman and sister ship Larne were ordered to investigate sightings of submarines off the Outer Hebrides.

[12] After these operations finished, Rifleman's division escorted the battleship Conqueror to Liverpool, arriving on 14 February, before setting off for Scapa Flow.

[15] On 1 January 1917 the German U-boat UB-47 torpedoed the Cunard liner RMS Ivernia off Cape Matapan, Greece.

[16] On 15 April 1917 the SS Cameronia was en route from Marseilles to Alexandria, Egypt, when the German U-boat U-33 torpedoed her 150 miles (240 km) east of Malta.
