HMS Obdurate was an Admiralty M-class destroyer which served with the Royal Navy during the First World War. The M class were an improvement on the previous L-class, capable of higher speed. Launched on 21 January 1916 by Scotts of Greenock, the vessel served as part of the Grand Fleet in the Battle of Jutland in May 1916. The destroyer formed part of the cover for the British battlecruisers and was involved in attacks on German battleships and destroyers, but recorded no hits. The destroyer was also part of attack by Zeppelin on Sydney and the distant cover for the Second Battle of Heligoland Bight, but received only minor damage from the German airship. After the armistice, Obdurate was assigned to the Local Defence Force at Nore and sold to be broken up on 9 May 1921.
