The Triumph Mayflower was a small car from Britain's Triumph Motor Company and was produced from 1949 to 1953.

The car was the first small car to be built by Triumph under their new owners the Standard Motor Company and used a version of the pre-war Standard 10 side valve engine updated by having an aluminium cylinder head and single Solex carburettor. The engine developed 38 bhp (28 kW) at 4200 rpm. The 3 speed gearbox, with column shift, came from the Standard Vanguard and hadsynchromesh on all the forward ratios. There was independent suspension at the front using coil springs but a solid back axle and half elliptic leaf springs, also based on the one used on the Vanguard, was at the rear. The front suspension design went on to be used on the Triumph TR2. Lockheed hydraulic brakes were fitted.
