The 1955 Open Championship was the 84th Open Championship, played 6–8 July at the Old Course in St Andrews, Scotland. Peter Thomson won the second of three consecutive Open titles, two strokes ahead of runner-up John Fallon. Thomson won a total of five Claret Jugs, the last in 1965. Previously the 17th hole (the "Road Hole") was a par 5; for this Open it became a par 4, which reduced the course par from 73 to 72. The winner's share was increased from £750 to £1,000, while the others were unchanged, bringing the total purse to £3,750.
