Cosworth is a high-performance engineering company founded in London in 1958, specialising in engines and electronics for automobile racing (motorsport) and mainstream automotive industries. Cosworth is based in Northampton, England, with North American facilities in Indianapolis and Mooresville, North Carolina.

Cosworth has collected 176 wins in Formula One as engine supplier, ranking second with most wins behind Ferrari.

The company was founded as a British racing internal combustion engine maker in 1958 by Mike Costin and Keith Duckworth (COStin and duckWORTH).

Both of the co-founders being former employees of Lotus Engineering Ltd., Cosworth initially maintained a strong relationship with Colin Chapman and the initial revenues of the company came almost exclusively from Lotus. When the company was founded in 1958, Duckworth left Lotus, leaving Costin (who had signed a term-employment contract with Chapman) at the company. Until 1962, Costin worked on Cosworth projects in his private time, while being active as a key Lotus engineer on the development of Lotus 15 through 26 (Elan), as well as leading the Team Lotus contingent at foreign races as evidenced by the 1962 Le Mans Lotus scandal.

Initial series production engines (Mk.II, Mk.V, Mk.VIII and Mk.XIV) were sold to Lotus exclusively, and many of the other racing engines up to Mk.XII were delivered to Team Lotus. The success of Formula Junior engines (Mk.III, IV, XI and XVII) started bringing in non-Lotus revenues, and the establishment of Formula B by SCCA in America allowed the financial foundation of Cosworth to be secured by the increased sales of Mk.XIII, a pure racing engine based on Lotus TwinCam, through its domination of the class. This newly found security enabled the company to distance itself from the Lotus Mk.VII and Elan optional road engine assembly business, and allowed its resources to be concentrated on racing engine development.
