Hansjörg Trachsel (born 30 August 1948) is a Swiss politician and former bobsledder who competed in the late 1970s.

Trachsel served as an officer in the international governing body of the sport, the Federation Internationale de Bobsleigh and Toboggan (FIBT), where he oversaw the construction and renovation of several bobsled venues.

A civil engineer by trade, he insured the required specifications, quality and schedule for sliding sport venues, including the Olympic tracks in Park City, Utah and Lake Placid, New York, and he provided early engineering guidance for the design of the Olympic track at Whistler Mountain for the 2010 Olympic Winter Games.

Elected in September 2004 to the Government of the canton of Grisons, Trachsel served a full 10-year tenure as the head of Economic and Social affairs.

In January 2015 it was announced that Trachsel would serve as President of Innozet, an incubator for technology start-up companies.
