The Studebaker Light Four was an automobile produced by the Studebaker Corporation of South Bend, Indiana in 1918 and 1919. The car was officially designated Model SH Series 19 and available as a touring car, sedan and roadster.

The Light Four rode a 112 in (2,800 mm) wheelbase, and was powered by Studebaker's inline 192 cu in (3,150 cc) four-cylinder engine, delivering 40 bhp (30 kW) at 2,000 rpm.

The Light Four was dropped in 1920 as Studebaker shifted its model range exclusively to six-cylinder engines.

Because of its low production numbers, the Light Four is considered to be a rare model by Studebaker collectors of this era of automobile.
