Jarmo Sakari Sandelin (born 10 May 1967) is a Swedish professional golfer who plays on the European Senior Tour.

He won the Turespana Open De Canaria during his début season as he finished in 21st place on the Order of Merit and was named the Sir Henry Cotton Rookie of the Year.

He also made his only Ryder Cup appearance that year, but was only selected to play in the singles and lost his match against Phil Mickelson 5 and 3.

[3] The European Tour tournament Lancome Trophy at Golf de Saint-Nom-la-Bretèche, 30 km west of Paris, France in September 1997, was won by Mark O'Meara, one stroke ahead of Sandelin.

O'Meara insisted he had not intended to gain any advantage and sought advice from the PGA and European Tours, who informed him that the tournament was over and the result stood.
