Jens Byggmark (born 22 August 1985) is a Swedish former World Cup alpine ski racer[1] who specialised in the technical events of slalom and giant slalom.

He raced for Tärna IK Fjällvinden, the world's most successful ski club.

Byggmark made his World Cup debut in 2005, and has won two slalom events, both during the 2007 season, on successive days at Kitzbühel, Austria.

After having struggled for some years with poor results and bad starting positions, Byggmark made a strong comeback during the 2011 season and for two seasons he had a place in the first start group.

In September 2013, he suffered a knee injury and missed the 2014 season, including the Olympic Games.
