AC Ace is a car which was produced by AC Cars of Thames Ditton, England, from 1953 until 1963. About 220 AC Aces and 466 Ace-Bristol cars were produced during its 10 year run.

AC Cars, originally incorporated as Auto Carriers Ltd., is a British specialist automobile manufacturer and one of the oldest independent car makers founded in Britain. As a result of bad financial conditions over the years, the company was renamed or liquidated many times until its present form. In 2022, the new corporate structure began the production of new AC Cobra models, with a slightly modified structure to adapt it to modern safety and technology requirements and obtain the European road homologation certificate.
