The R&A is the collective name of a group of companies that together play a significant role within the game of golf. Historically, "the R&A" was a colloquial name for the Royal and Ancient Golf Club of St Andrews; in 2004, the club spun off its previous governance and tournament organisation roles into the current R&A group, with the club itself reverting to a private members-only club. The R&A is based in St Andrews in Scotland. The R&A is the sole owner of three subsidiary companies: R&A Rules Limited, R&A Championships Limited, and R&A Group Services Limited.

The R&A World Golf Museum is located opposite the clubhouse of the Royal and Ancient Golf Club in St Andrews, Scotland. The R&A owns and operates the museum.
