Vice Admiral Sir Ian Leslie Trower Hogg (30 May 1911 – 2 March 2003) was a Royal Navy officer whose service extended from the late 1920s through to the early 1970s. He received several medals for his service as a navigator during the Second World War. From 1967 to 1970 he served as Vice-Chief of the Defence Staff.

His war career showed that he was clearly able to differentiate the important from the unimportant and to "bear an even strain" under testing circumstances. Second World War Hogg was awarded the first of his two Distinguished Service Crosses (DSC) for his efficiency and coolness as a navigator under the trying circumstances of the evacuation of Crete in May and June 1941. The Germans had intended to take Crete with combined airborne and seaborne attacks. Although the Royal Navy was able virtually to annihilate the seaborne component, which carried much equipment in local caïques, the German paratroops—though at great loss to themselves—forced the under-equipped British forces, many of whom were still in shock after being driven out of Greece, into another evacuation. Air attacks by an almost unopposed and expert Fliegerkorps VIII around Crete cost the British three cruisers and six destroyers sunk, with an aircraft carrier, two battleships, five cruisers and seven destroyers badly damaged, bringing the
