Royal Air Force Linton-on-Ouse or more simply RAF Linton-on-Ouse (IATA: HRT, ICAO: EGXU) is a former Royal Air Force station at Linton-on-Ouse in North Yorkshire, England, 10 miles (16 km) north-west of York. It had satellite stations at RAF Topcliffe and Dishforth Airfield (British Army).

The station opened in 1937. With the transfer of pilot training to RAF Valley on Anglesey in 2019, the station closed in 2020. In February 2021, the MOD confirmed that no alternative military use had been identified for the site and that it would therefore be sold.

RAF Linton-on-Ouse opened on 13 May 1937 as a bomber airfield and was the home of No. 4 Group RAF until 1940. The base's first commander was Wing Commander A. D. Pryor.

When the Second World War began, bombers were launched from Linton to drop propaganda leaflets over Germany and the base was eventually used to launch bombing raids on Norway, The Netherlands, Germany, and Italy. Linton was one of 11 stations allocated to No. 6 Group, Royal Canadian Air Force during the war.

In May 1941 the station was bombed by the Luftwaffe resulting in the death of 13 airmen including the station commander, Group Captain Garroway. A York Press article refers to the 'mystery' of how Garroway was killed – the station's record books state he was directing firefighting when he met his death, not taking shelter. His son, who was also in the RAF, was later killed in action.

At the end of the war the station was involved with transporting passengers and freight back to the UK. After which it became a Fighter Command station operating the Gloster Meteor, Canadair Sabre and Hawker Hunter until it was closed and put under care and maintenance in 1957.

On 9 September 1957, the base was reopened as the home of No. 1 Flying Training School (FTS) and was responsible for training pilots for both the RAF and the Royal Navy's Fleet Air Arm.

In October 1975 Headquarters No. 23 Group RAF disbanded at the station.
