The Landing Craft Infantry (LCI) were several classes of landing craft used by the Allies to land large numbers of infantry directly onto beaches during World War II. They were developed in response to a British request for seagoing amphibious assault ships capable of carrying and landing substantially more troops than their smaller Landing Craft Assault (LCA). The result was a small steel ship that could land 200 men, traveling from rear bases on its own bottom at a speed of up to 15 knots.

The U.S. Navy large infantry landing craft USS LCI(L)-551 in May 1945, flying her colors at half-mast in honor of the recently deceased President Franklin D. Roosevelt. Transferred to the Soviet Navy on 29 July 1945 during Project Hula, she became DS-48 and took part in the Soviet invasion of the Kuril Islands. The Soviet Union returned her to the United States in 1955.
The LCIs USS LCI(L)-585 and USS LCI(L)-591 at Cold Bay, Territory of Alaska, in the spring of 1945, awaiting transfer during Project Hula to the Soviet Navy, in which they became DS-45 and DS-35, respectively. The Soviets returned LCI(L)-585 to the United States in 1955; DS-35 was scrapped in the Soviet Union.
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States.
