The de Havilland Gipsy Minor or Gipsy Junior was a British four-cylinder, air-cooled, inline engine used primarily in the de Havilland Moth Minor monoplane, both products being developed in the late 1930s.

The engine was a simplified and smaller version of the earlier de Havilland Gipsy. It featured only one magneto where dual ignition was normal for the Gipsy series of engines. A total of 171 engines were produced, including 100 built in Australia, production moving to that country due to the start of the Second World War.
