The Triumph 1300 is a medium/small 4-door saloon car that was made between 1965 and 1970 by Standard Triumph in Coventry, England, under the control of Leyland Motors. It was introduced at the London Motor Show in October 1965 and intended as a replacement for the popular Triumph Herald. Its body was designed by Michelotti in a style similar to the larger Triumph 2000. It was replaced by the Triumph 1500, though it was also re-engineered in the early 1970s to provide the basis for the Toledo and Dolomite ranges.

The Triumph Herald is a small two-door car introduced by Standard-Triumph of Coventry in 1959 and made through to 1971. The body design was by the Italian stylist Giovanni Michelotti, and the car was offered in saloon, convertible, coupé, estate and van models, with the latter marketed as the Triumph Courier.
