3rd Polish Fighter Wing

3rd Polish Fighter Wing (3 Polskie Skrzydło Myśliwskie) was a mainly Polish formation that flew, Supermarine Spitfires of the Royal Air Force during the Second World War. It was part of the Polish Air Forces in France and Great Britain.

It was formed in June 1943, as the 2nd Polish Fighter Wing, from two Polish squadrons, the No. 302 Squadron RAF and No. 317 Squadron RAF. In September it was merged into the 1st Polish Fighter Wing (which was soon thereafter renamed the 131 Wing). It was reorganized in February 1944.

Its composition would not be stable, as the Polish Squadrons were frequently exchanged between three Polish wings (the No. 131 Wing RAF (1st Polish) wing, the No. 133 Wing RAF (2nd Polish) wing, and the 3rd Polish Fighter Wing).

At various times, this wing sported the other Polish squadrons, such as the No. 303 Squadron RAF and No. 316 Squadron RAF. The number of wings was also not constant, as it varied from at one to two.
