The Wolseley Motor Company was a British automobile manufacturer.

In 1895, Herbert Austin began developing tricycles at the Birmingham subsidiary newly formed by the Wolseley Sheep Shearing Company.
In 1896, the first Wolseley automobile was introduced.
Austin left the company in 1905 and started his own company.
Between 1905 and 1910, designer John Davenport Siddeley ran the company, and the cars were marketed as Wolseley-Siddeley.
During this period, the company developed the first snowmobile, which was used in the Terra Nova expedition (1910-1913) led by the British polar explorer Robert Falcon Scott. In memory of this, the Wolseley Buttress rock massif on the Antarctic Peninsula bears the name of the manufacturer.
During World War I, Wolseley produced Hispano-Suiza V8 aircraft engines under license.

In 1927, Wolseley went bankrupt and was acquired by Morris.
Since then, identical parts have been used in Morris, MG and Wolseley models.
After World War II, Wolseley models became increasingly similar to Morris models.
In 1949, production facilities were moved to the Morris plant in Cowley.
From then on, automobiles offered under the Wolseley brand name were merely more luxuriously equipped variants of Morris models (so-called badge engineering).
In 1975, the new parent company, British Leyland, ceased production of Wolseley-branded automobiles; the last Wolseley was a high-end version of the BLMC ADO71.
