Aintree Motor Racing Circuit is a disused 3-mile motor racing circuit in the village of Aintree, Liverpool, England. The circuit is located within the famous Aintree Racecourse and used the same grandstands as horse racing. Built in 1954 as the "Goodwood of the North", hence the fact the two venues had so many things in common.

The circuit has hosted the Formula One British Grand Prix five times, in 1955, 1957, 1959, 1961 and 1962.

In addition to the Grand Prix, the circuit also held 11 non-championship Formula 1 races, known as the Aintree 200, first won by Stirling Moss in 1954 with the last winner being Jack Brabham, in April 1964. Aintree was the location for the famous race in 1955 in which Stirling Moss won his first British Grand Prix, driving a Mercedes. Two years later, he and Tony Brooks (sharing the Vanwall) became the first British drivers to win both the British Grand Prix and a round of the Formula 1 World Championship, whilst driving a British car, a Vanwall. The 1957 Grand Prix also took the title of Grand Prix de Europe and was the premier Formula 1 event of the season, attracting 150 000 spectators. The full Grand Prix circuit was last raced on in 1964, but part of it (the Club Circuit) is still open and was used for racing until the early 1980s, having been maintained and operated by the Aintree Circuit Club[745109] since the mid 1960s. A limited amount of motor sport continues today in the form of car sprints, track days and motorcycle racing.

At present time, the track is often used by young karting schools and events.

A manager at Aintree Race-course on 28 May 2009 announced that they and Liverpool city council are currently considering whether to turf over the track or redevelop it and bid to bring back small single seat racing events like Formula Palmer Audi, Formula Ford and Formula Renault. This is with the intention of re-starting motor racing events at the track in 2010 at the earliest.
