The Mauboussin M.120 was a trainer and touring aircraft built in France in the 1930s and again in the years following World War II.
In 1936, Fouga, then a builder of railway rolling stock, purchased all rights to the design as part of an effort to enter the aircraft industry, and was able to secure a contract from the Armée de l'Air to supply the type as the M.123.
Production was restarted by Fouga after the war for the French flying clubs.
