The 57th Weather Reconnaissance Squadron is an inactive United States Air Force squadron. Its last assignment was with the 9th Weather Reconnaissance Wing at Hickam Air Force Base, Hawaii, where it was inactivated on 10 November 1969.

Activated in early 1943 under Fourth Air Force; spent World War II in the United States as an Operational Training Unit, initially equipped with Bell P-39 Airacobras for advanced fighter training. Reassigned to Third Air Force in 1944, becoming a Replacement Training Unit for North American A-36 Apache fighter-dive bomber ground attack aircraft.

The squadron moved to Stuttgart Army Air Field Arkansas in 1945 and realigned into a long-range strategic weather reconnaissance squadron, training with B-25 Mitchells and long-ranger P-61C Black Widow Night Fighters modified for weather reconnaissance missions. Moved to Rapid City Army Air Feild, South Dakota in late 1945, using P-61Cs as part of a NACA/Air Weather Service Thunderstorm Project to learn more about thunderstorms and to use this knowledge to better protect civil and military airplanes that operated in their vicinity. The Northrop P-61 Black Widow's radar and particular flight characteristics enabled it to find and penetrate the most turbulent regions of a storm, and return crew and instruments intact for detailed study. Inactivated in 1946 as part of the general demobilization of the Army Air Forces.

The squadron was activated in the reserve in July 1947 at Hamilton Field. However, it is not clear that it was manned or equipped beyond a token cadre before President Truman’s reduced 1949 defense budget required reductions in the number units in the Air Force, and the squadron was inactivated in June 1949.
