The Walker Cup Match is a biennial match-play contest played between two 10-man amateur teams from the United States of America and Great Britain & Ireland. Organized by the R&A and USGA, the event is played alternatively on either side of the Atlantic, with each competition played over two days of foursomes and singles matches.

The first edition of The Walker Cup was held at the National Golf Links of America in 1922 and, until 1961, games were played over 36 holes; four foursomes on the first day and eight singles on the second day.

Thereafter, the format changed to 18-hole ties, allowing four foursomes in the morning and eight singles in the afternoon on both days. Since 2009, ten singles are played on the second day, guaranteeing all team members at least one match.

The trophy is named after George Herbert Walker, who was president of the USGA in 1920 when thoughts of organising the tournament were first raised. Walker was the maternal grandfather of President George H. W. Bush and therefor great grandfather of President George W. Bush. Born in St. Louis, Missouri, Walker was educated in England and the US before starting a banking and investment firm in 1900, from where he developed many useful contacts, both in and out of golf.

The players with most appearances on either team are Joe Carr of GB&I, who played in ten events between 1947 and 1967, and Jay Seigel of the USA, who represented his country nine times from 1977 to 1993.

The largest winning margins are all in favour of the United States, who have dominated the competition right from the beginning, winning three out of every four tournaments ever played: Scott Hoch crushed James Buckley 9&7 over 18 holes at Muirfield in 1979 and Booby Jones trounced Philip Perkins 13&12 in their 36-hole tie at Chicago in 1928.

The Old Course has hosted the Walker Cup a record eight times (1923 to 1975) and the contest has also taken place at seven Royal venues, the last of which was Royal Aberdeen in 2011, where the home team celebrated a rare victory by 14 points to 12. Seven clubs have each held The Walker Cup twice; the first to do so was The Country Club in Brookline in 1973 and the last was Royal Liverpool in 2019.
