The 1935 Open Championship was the 70th Open Championship, played 26–28 June at Muirfield in Gullane, East Lothian, Scotland. Alf Perry won his only major title, four strokes ahead of runner-up Alf Padgham.
Qualifying took place on 24–25 June. Entries played 18 holes at Muirfield and 18 holes at the number 1 course Gullane. The top 100 and ties qualified. The qualifying score was 153 and 109 players qualified. Henry Cotton led the qualifiers on 141. The top 60 and ties would make the cut and qualify for the final 36 holes.
Defending champion Henry Cotton took the first round lead after an opening 68, with Alf Perry a stroke behind. Charles Whitcombe carded his own round of 68 in the second round and took the lead by three over Cotton and Alf Padgham after 36 holes, with Perry falling five back. In the third round it was Perry who caught fire, shooting a 67 and moving ahead of Cotton and Whitcombe, who shot 76 and 73, respectively. A 72 in the final round was enough for Perry to prevail by four over Padgham. Whitcombe finished in third place, while Cotton fell to seventh with a final round 75. Amateur Lawson Little, the reigning British Amateur champion, finished in a tie for 4th. Perry's winning total of 283 equaled the tournament scoring record.
Perry's win was the first of any kind for him as a professional golfer, and he only won three more times. He finished in third place in the 1939 Open, but otherwise had no other top-10 finishes in a major championship. He was a member of three Ryder Cup teams.
