454 Squadron was a unit of the Royal Australian Air Force (RAAF) that served during World War II.

It was re-formed later in 1941 from mainly British personnel and subsequently took part in the fighting in the Mediterranean and Middle East theatre before being disbanded in August 1945.

From July 1944, the squadron was committed to the Italian campaign, moving to Pescara, where it was assigned to the Desert Air Force.

According to the Australian War Memorial, 454 Squadron "earned a reputation for efficiency, despite Italy's climatic extremes", utilising techniques such as radar-controlled bombing.

In early 1945, 454 Squadron converted to the night intruder role, attacking German forces as they withdrew north.
