Markus Gandler (born August 20, 1966 in Kitzbühel) is former cross country skier from Austria who competed from the late 1980s to the late 1990s.
At the 1989 FIS Nordic World Ski Championships in Lahti, his team ranked 11th in the 4 × 10 km relay. In the winter of 1989/1990 he had his best World Cup finish with a third in Canmore, Canada.
He won an Olympic silver medal in the men's 10 km at the 1998 Winter Olympics in Nagano.
At the 1999 FIS Nordic World Ski Championships in Ramsau, he won gold in 4 × 10 km relay with his relay teammates Alois Stadlober, Mikhail Botwinov, and Christian Hoffmann.
Since 2003, and also at the 2006 Winter Olympics in Turin, Italy he has been director of the Austrian biathlon and cross-country teams.
He received a life ban from the Austrian Olympic Committee in 2007 as one of 14 team officials who were implicated in doping activity at the 2006 Winter Olympics. The bans on Gandler and 11 others were subsequently rescinded in 2009, after the Fédération Internationale de Ski dropped doping charges against Gandler, biathlon coach Alfred Eder and cross-country ski coach Gerald Heigl.
