No. 302 (City of Poznań) Polish Fighter Squadron RAF was a Polish fighter squadron formed in the United Kingdom as part of an agreement between the Polish Government in Exile and the United Kingdom in 1940. It was one of four Polish-cored RAF squadrons that participated in the Battle of Britain.

The squadron was formed on 10 July 1940, equipped with Hawker Hurricanes and initially based at RAF Duxford as part of No. 12 Group RAF. It operated as part of the Duxford Wing — 12 Group's famous "Big Wing" formation — from 14 September through 25 September 1940, conducting intercepting operations against German bomber formations attacking London and other targets.

After the Battle of Britain, the squadron undertook coastal patrols and night-flying training before transitioning to night fighter operations. Post-war, the squadron was employed on fighter-bomber duties before eventually disbanding in December 1946, completing a distinguished six-year record of service with the RAF.
