The McCawley-class attack transport was a class of US Navy attack transport built in 1928 that saw service in World War II.

Like all attack transports, the purpose of the McCawley-class ships was to transport troops and their equipment to hostile shores in order to execute amphibious invasions. Attack transports carried a substantial number of integral landing craft for making the assault, and were well armed with antiaircraft weaponry to protect themselves and their vulnerable cargo of troops from air attack in the battle zone.
