The Norton International was a British motorcycle made by Norton Motorcycles between 1931 and 1939. A TT replica sports roadster, production of the Model 30 International ended on the outbreak of World War II.

The name International was first used by Norton for its TT replica sports roadster in 1932. Designed by Joe Craig, Arthur Carroll designed an overhead-camshaft engine for the works racers and although it retained the 79 x 100mm bore and stroke of the Norton CS1 the Model 30 was new. The racing heritage led to quickly detachable wheels and hairpin type valve springs that could be changed rapidly when racing. In 1933 the forks and gearbox were redesigned and in 1935 the Sturmey-Archer gearbox was replaced, as Sturmey-Archer had stopped making gearboxes, so Norton bought the rights to the design and commissioned Burman’s to produce them. These gearbox’s proved so good they remained unchanged for the next 30 years.

In 1936 the engine was upgraded with an alloy head and barrel with a bronze liner. In 1938 suspension was upgraded to plunger type Production of the Model 30 ended on the outbreak of World War II. After the war production of the International Model 40 (350cc) restarted with an iron head and barrel, as fitted to the pre-war CS1 and CJ Nortons. The suspension was upgraded to Norton Roadholder telescopic forks instead of girders and "Clubmans" versions were produced without silencers and lights for racing use. Close ratios gearboxes were supplied as standard from 1947 and the alloy engine made a comeback in 1953 with a new version of the Featherbed frame. Volume production of the International ended in 1955 although small numbers were built to special order for two or three years after.
