Desoutter is a British monoplane liaison aircraft manufactured by Desoutter Aircraft Company at Croydon Aerodrome, Surrey.

In the late 1920s, Marcel Desoutter, the famous pilot, formed the Desoutter Aircraft Company Ltd to follow up his marketing idea to licence manufacture the Dutch aircraft Koolhoven F.K.41. This aircraft had drawn a lot of attention due to its modern design. The licence was obtained and Desoutter set up a production unit at Croydon Aerodrome in the former ADC Aircraft factory.

The second production Dutch F.K.41 (registered G-AAGC) was flown to Croydon and was modified by Desoutter and displayed at the Olympia Aero Show, London in July 1929 as the Desoutter Dolphin. This aircraft was later sold in South Africa with registration ZS-ADX and was impressed into service with the South African Air Force.

The name Dolphin was not used again and the British production aircraft was known as the Desoutter and then following the introduction of an improved version the following year the Desoutter I. The National Flying Services Ltd placed a large order and received 19 aircraft. These were all painted black and bright orange and soon became a familiar sight at British flying clubs, where they were used for instruction, pleasure flights and taxi flights. The first aircraft for another customer left Croydon for New Zealand on 9 February 1930. It was flown to Sydney, Australia arriving on 13 March 1930, it was then shipped to New Zealand.

In 1930 an improved version, the Desoutter II was produced. It had a de Havilland Gipsy III engine, redesigned ailerons and tail surfaces and wheel brakes.
