The World Senior Championship was a golf match held between the winners of the American PGA Seniors' Championship (now Senior PGA Championship) and the British PGA Seniors Championship. It was held from 1954 to 1978. It was a 36-hole match-play event held on a single day with the exception of the first year when it was held over two days. The British PGA Seniors Championship did not start until 1957. In 1954 and 1955 the British competitor was nominated by the British Association of Golf Writers while in 1956 four leading senior golfers played to decide the British entry.
