1965 Open Championship

The 1965 Open Championship was the 94th Open Championship, played 7–9 July at Royal Birkdale Golf Club in Southport, England. Peter Thomson won his fifth Claret Jug, two strokes ahead of runners-up Brian Huggett and Christy O'Connor Snr. Thomson's previous Open victory was seven years earlier in 1958.
