RAF Cranwell is a Royal Air Force station in Lincolnshire near the village of Cranwell.

Cranwell is home to the Royal Air Force College (RAFC), which trains the RAFs new officers on a 26-week course. It is thus the RAF equivalent of Sandhurst or the Britannia Royal Naval College, and is considered by some to be the spiritual home of the RAF.

No.3 Flying Training School (FTS), training navigators and non-commissioned aircrew, is also based there. Cranwell is also home to two of the RAF bands.

Since the mid-1990s, Cranwell has been home to Headquarters, Air Cadets.
