Lieutenant-Colonel Frederick Frank Reilly Minchin CBE DSO MC (16 June 1890 – disappeared 31 August 1927) was a British pilot of the Royal Air Force.
In 1915 he transferred to the Royal Flying Corps (RFC) with the rank of lieutenant and in 1916 was awarded the Military Cross for his daring night bombing flights into enemy territory over Egypt and Palestine.
In July 1919 he served in India and was appointed a Commander of the Order of the British Empire (CBE) having gained three awards for gallantry and mentioned in dispatches on three occasions.
On 31 August 1927, Lieutenant-Colonel Minchin, Captain Leslie Hamilton and Princess Anne of Löwenstein-Wertheim-Freudenberg took off from Upavon airfield in a Dutch Fokker F.VIIA named the St. Raphael in a bid to become the first aviators to cross the Atlantic from east to west.
The St Raphael was never seen again, and the fate of Lieutenant Colonel Minchin, Captain Leslie Hamilton and Princess Loewenstein-Wertheim remains a mystery.
