The Hawthorn M (or Mansfield) Class were a class of two destroyers built for the Royal Navy under the pre-war 1913-14 Programme for World War I service.

They were similar to the Admiralty M class, but completed to a modified design by Hawthorn Leslie and Company, Hebburn on Tyne. They had four funnels instead of the three funnels of the Admiralty design; as a consequence, they were the last four-funnelled destroyers (apart from Leaders) to be built for the Royal Navy. The midships 4 inch gun was shipped between the second and third funnels. Both ships were laid down on 9 July 1914 and completed in 1915. Both survived the war and were scrapped in 1921,

Hawthorn Leslie subsequently received orders for two further M class destroyers as part of the large batch of orders placed in May 1915, but these two - Pidgeon and Plover - were built to the Admiralty M class design.
