RAF Innsworth was a non-flying Royal Air Force station, located on the North side of the city of Gloucester in England.

The site was transferred to the British Army and renamed Imjin Barracks, becoming the home of the Allied Rapid Reaction Corps in 2010.

More than 2,000 officers and men were based at Innsworth by the time training began, in earnest, in 1941, this being delayed due to the arrival of 1500 RAF evacuees from Dunkirk.

In 1951, the headquarters of the RAF Record Office, which had been based nearby in Gloucester and Barnwood, moved to the station and gained Group status.

In March / April 2005 the MOD Medals Office and Joint Casualty and Compassionate Centre (JCCC) were established at Innsworth under AFPAA management.

In 2010, the station also became home to the NATO Allied Rapid Reaction Corps, which relocated to Innsworth from the Rheindahlen Military Complex in Germany.
