The 1862 Open Championship was the third Open Championship and was again held at Prestwick Golf Club, Ayrshire, Scotland.

Four professionals and four amateurs contested the event, with Tom Morris, Sr. winning the championship for the second time, by 13 shots from Willie Park, Sr. As in previous years, the contest was held over three rounds of the 12-hole links course.

There was no prize money, the winner receiving the Challenge Belt for the next year.

Eventually Morris won by 13 strokes, which remains the record margin of victory in the Open Championship.

[1] It was also the record margin of victory for any major championship until Tiger Woods won the 2000 U.S. Open at Pebble Beach by 15 shots.
