Martin Larsson is a Swedish cross-country skier who competed between 1999 and 2011. He won a bronze medal in the 4 × 10 km relay at the 2007 FIS Nordic World Ski Championships in Sapporo and finished 79th in the 15 km event at those same championships.

The FIS Nordic World Ski Championships 2007 took place 22 February – 4 March 2007 in Sapporo, Japan. It was the second time this city has hosted these championships, having previously done so in the 1972 Winter Olympics. Sapporo was selected as venue by vote at the 43rd FIS World Congress in Portorož, Slovenia, on 6 June 2002. It also marked the third time the championships were hosted outside Europe in a year that did not coincide with the Winter Olympics; it was the first championship held in Asia. The ski jumping team normal hill event was not held, as it had been in 2005.
