Connaught Engineering, often referred to simply as Connaught, was a Formula One, Formula Two and other sports car divisions constructor from the United Kingdom. Their cars participated in 18 Grands Prix, entering a total of 52 races with their A, B, and C Type Formula 2 and Formula 1 Grand Prix Cars. They achieved 1 podium and scored 17 championship points. The name Connaught is a pun on Continental Autos, the garage in Send, Surrey, which specialised in sales and repair of European sports cars such as Bugatti, and where the cars were built.

Formula Two is a type of open-wheel formula racing category first codified in 1948. It was replaced in 1985 by Formula 3000, but revived by the FIA from 2009–2012 in the form of the FIA Formula Two Championship. The name returned again in 2017 when the former GP2 Series became known as the FIA Formula 2 Championship.
