No. 189 Squadron was a Royal Air Force squadron.

The squadron was formed at Royal Flying Corps Ripon (RFC Ripon) on 20 December 1917 as a night-flying training unit, moving shortly afterwards to Sutton's Farm.{{cite book |last1=Chorlton |first1=Martyn |title=Forgotten aerodromes if World War I |date=2014 |publisher=Crecy |location=Manchester |isbn=9780859791816 |page=171}} This work continued until the end of World War I. On 1 March 1919, the squadron was disbanded.

The squadron was re-formed as part of No. 5 Group RAF on 15 October 1944 at RAF Bardney near the village of Bardney in Lincolnshire. However, Jefford in RAF Squadrons lists the reformation date as November 1944.{{sfn|Jefford|1988|page=66}}

The squadron flew Avro Lancaster bombers in raids over occupied Europe in 1944 and 1945.

The commanding officer was Wing Commander J. S. Shorthouse. Shorthouse had been born in Portsmouth in England in April 1920; joined the Royal New Zealand Air Force in April 1939; and transferred to the RAF in January 1940.{{sfn|Thompson|1956|page=402}} He commanded the squadron in 1944-1945. He was awarded the Distinguished Flying Cross for an operation that predated his command of the squadron: he gained his DFC on 2 November 1943 for a bombing raid in September 1943.

After RAF Bardney, the squadron was based at RAF Fulbeck near the village of Fulbeck, returning to Bardney in April 1945 and then on to RAF Metheringham near Metheringham.

The unit was mixed, with many personnel from other parts of the Commonwealth including Australians, New Zealanders and Canadians.

No. 189 Squadron was among the 107 Lancasters and 12 Mosquitos of No 5 Group which attacked the oil refinery in Tonsberg in Southern Norway on 25 April 1945 in the last raid of the war flown by heavy bombers of RAF Bomber Command.

In July 1945 the Commanding Officer, Wing Commander Shorthouse, transferred back from the RAF to the RNZAF.{{sfn|Thompson|1956|page=402}}

After the war the unit was involved in dropping food to the Dutch and repatriating POWs until it was disbanded on 20 November 1945.
