Tony Jacklin (born July 7, 1944) is an English golfer, who was arguably the most successful UK player of his generation.

Jacklin won two majors. In 1969, he became the first British player to win The Open Championship for 18 years. The following season he won the U.S. Open. It was the first victory by a British player in that tournament since 1920, and as of 2004, it remained the only one by any European in the post World War II era.

On the PGA European Tour Jacklin recorded 10 victories between 1970 and 1982. He had further wins in the United States, South America, South Africa and Australasia.

However, Jacklin may be best remembered for his involvement in the Ryder Cup. He was a playing member of the "Great Britain and Ireland" team in 1967, 1969, 1971, 1973, 1975 and 1977, and of the first European team in 1979. Except for a tie in 1969, all of those teams were defeated, but as the non-playing captain of Europe in four consecutive Ryder Cups from 1983 to 1989, he had a 2.5 - 1.5 winning record, captaining his men to their first victory for 28 years in 1985, and to their first victory in the United States since the War in 1987.

Jacklin retired from tournament golf in 2004 at the age of sixty, having won a number of events at senior level.
