Landing Ship, Tank (LST), or tank landing ship, is the naval designation for ships built during World War II to support amphibious operations by carrying tanks, vehicles, cargo, and landing troops directly onto shore with no docks or piers. This provided amphibious assaults to almost any beach. The bow of the LST had a large door that would open with a ramp for unloading the vehicles. The LST had a special flat keel that allowed the ship to be beached and stay upright. The twin propellers and rudders had protection from grounding. The LSTs served across the globe during World War II including: Pacific War and European theatre.

The first tank landing ships were built to British requirements by converting existing ships; the UK and the US then collaborated upon a joint design. Over 1,000 LSTs were laid down in the United States during World War II for use by the Allies. Eighty more were built in the United Kingdom and Canada.

The British evacuation from Dunkirk in 1940 demonstrated to the Admiralty that the Allies needed relatively large, ocean-going ships that could handle shore-to-shore delivery of tanks and other vehicles in amphibious assaults upon the continent of Europe. As an interim measure, three 4,000- to 4,800-GRT tankers, built to pass over the restrictive bars of Lake Maracaibo, Venezuela, were selected for conversion because of their shallow draft. Bow doors and ramps were added to these ships, which became the first tank landing ships, "LST (1)": HMS Misoa, Tasajera and Bachaquero. They later proved their worth during the invasion of Algeria in 1942, but their bluff bows made for inadequate speed and pointed out the need for an all-new design incorporating a sleeker hull.
