Mårten Olander (born 5 November 1971) is a Swedish professional golfer.

He returned to the Challenge Tour for 1999, and spent three further seasons there before winning his first professional tournament at the 2001 Hardelot Challenge de France, sealing his return to the full European Tour.

[1] He spent a further five seasons at the highest level, before a dramatic slump in form saw him make only three cuts in 2006, since when he has played rarely.

Olander's best result on the European Tour was a four-way tie for second at the 2003 Telefonica Open de Madrid.

In 2008, Olander was joint captain of the successful European Palmer Cup team.
