The 55th (West Lancashire) Infantry Division was an infantry division of the British Army's Territorial Army (TA) that was formed in 1920 and existed through the Second World War, although it did not see combat. The division had originally been raised in 1908 as the West Lancashire Division, part of the British Army's Territorial Force (TF). It fought in the First World War, as the 55th (West Lancashire) Division, and demobilised following the fighting. In 1920, the 55th (West Lancashire) Division started to reform. It was stationed in the county of Lancashire throughout the 1920s and 1930s, and was under-funded and under-staffed. In the late 1930s, the division was reduced from three to two infantry brigades and gave up some artillery and other support units to become a motorised formation, the 55th (West Lancashire) Motor Division. This was part of a British Army doctrine change that was intended to increase battlefield mobility.

Following the German occupation of Czechoslovakia, the division created new units around cadres of its own personnel, a process called "duplicating". The division then used these new formations to create its "duplicate", the 59th (Staffordshire) Motor Division. The 55th remained in the United Kingdom, in a defensive role, after the outbreak of the Second World War. In 1940, following the Battle of France, the motor division concept was abandoned. The division regained its third infantry brigade, and became the 55th (West Lancashire) Infantry Division. It remained within the United Kingdom, training for future operations as well as training replacements for combat units, and assigned to anti-invasion duties. By 1944, the division had been drained of many of its assets. The remnant of the division was used in Operation Fortitude, a deception effort that supported the Allied invasion of France. At the end of the war, the division was demobilised and not reformed.
