The Laforey class (redesignated in October 1913 as the L class) was a class of 22 torpedo boat destroyers of the Royal Navy, twenty of which were built under the Naval Programme of 1912–13 and a further two under the 2nd War Emergency Programme of 1914. As such they were the penultimate pre-war British destroyer design (the M class built under the Naval Programme of 1913–14 being the last design). All served during World War I during which three were lost; the survivors were all scrapped in 1921-23.
