Marylebone Cricket Club (MCC) is a cricket club founded in 1787 and based since 1814 at Lord's Cricket Ground, which it owns, in St John's Wood, London. The club was formerly the governing body of cricket retaining considerable global influence.

In 1788, the MCC took responsibility for the laws of cricket, issuing a revised version that year. Changes to these Laws are now determined by the International Cricket Council (ICC), but the copyright is still owned by MCC. When the ICC was established in 1909, it was administered by the secretary of the MCC, and the president of MCC automatically assumed the chairmanship of ICC until 1989.

For much of the 20th century, commencing with the 1903–04 tour of Australia and ending with the 1976–77 tour of India, MCC organised international tours on behalf of the England cricket team for playing Test matches. On these tours, the England team played under the auspices of MCC in non-international matches. In 1993, its administrative and governance functions were transferred to the ICC and the Test and County Cricket Board (TCCB).

MCC teams are essentially ad hoc because they have never taken part in any formal competition, but have always held first-class status when playing against first-class opposition. By tradition, to mark the beginning of each English season, MCC plays the reigning county champions.

The present president of the club is Stephen Fry, who assumed the twelve-month office on 1 October 2022, replacing Clare Connor, the first woman to hold the post.
