The
Walker Cup is a golf trophy contested in odd-numbered years by leading male amateur golfers in two teams: United States, and Great Britain and Ireland featuring players from the United Kingdom and Ireland. The official name is the
Walker Cup Match. It is organised by The R&A and the United States Golf Association (USGA). In 1921 the Royal Liverpool Golf Club hosted an unofficial contest which was followed by official annual contests from 1922 through 1924. From 1925 they became biennial, held on even-number years. After World War II they switched to odd-numbered years. From 2026 it will be held in even-numbered years following the switch of the Eisenhower Trophy to odd-numbered years to avoid that event clashing with the Olympic Games. They are held alternately in the U.S., and Ireland or Britain.
