The 1905 Open Championship was the 45th Open Championship, held 7–9 June at the Old Course at St Andrews, Fife, Scotland. James Braid won the Championship for the second time, by five strokes from runners-up Rowland Jones and J.H. Taylor.
All entries played 18 holes on the first two days with all those within 14 strokes of the leader making the cut and playing 36 holes on the final day.
Strong winds and hard ground conditions made scoring difficult on all three days and there were few rounds under 80. Sandy Herd, Taylor, Walter Toogood and Harry Vardon led after the first round with scores of 80. Scoring was slightly better on the second day with Jones's 77 giving him the lead on 158. He was followed by Braid on 159 and James Kinnell and Arnaud Massy on 161. Just 45 players made the cut of 172, including a sole amateur John Graham, Jr.
On the final morning, Braid scored 78 to take a six shot lead over Kinnell, Massy and Taylor. Jones took 87 and dropped eight strokes behind Braid. Scoring 81 in the afternoon Braid was never challenged. He reached the turn in 38 and despite taking six at the 15th and 16th holes, came back in 43. Jones's 78 moved him into second place, tied with Taylor but five strokes behind the champion.
