The Persian Gulf Command was a United States Army service command established in December 1943 to facilitate the supply of US lend-lease war material to the Soviet Union, through the "Persian Corridor".

The Persian Corridor was a supply route through Iran into Soviet Azerbaijan by which British aid and American Lend-Lease supplies were transferred to the Soviet Union during World War II. Of the 17.5 million long tons of US Lend-Lease aid provided to the Soviet Union, 7.9 million long tons (45%) were sent through Iran.
