Jan Bos (born 29 March 1975) is a Dutch former speedskater and sprint cyclist.

In the late 1990s he was world champion in speed skating and he competed in the 1998, 2002, 2006 and 2010 Winter Olympics.

In 2012 Bos (in cooperation with the Human Power Team from Delft) tried to become the fastest cyclist in the world during the World Human Powered Speed Challenge in Battle Mountain, Nevada.

At the time, the International Human Powered Vehicle Association record was 133 km/h, held by the Canadian Sam Whittingham.

[2] Bos used a recumbent bicycle specially developed for the occasion by students of the Delft University of Technology and the Vrije Universiteit Amsterdam, but only managed a maximum speed of 126.5 km/h.
