Task Force 57 (TF 57) is a US Navy task force. It was previously active during World War II. Task Force numbers were in constant use, and there were several incarnations of TF 57 during World War II. Land based bombers of the United States Air Force's Seventh Air Force were part of TF 57 during 1943–1944. The British Pacific Fleet was allocated as TF 57 in 1945 before being redesignated Task Force 37 in May. During the Cold War, Task Force 57 was allocated to the United States Pacific Fleet, and available for use, though it was little publicised.
