Andrew Fenn (born 1 July 1990) is a British cyclist, who rode for Scotland in the 2010 Commonwealth Games and rides for Aqua Blue Sport.
Fenn competed in many sports as a child but concentrated on cycling from the age of 12 when he joined Welwyn Wheelers. His talent was noticed by British Cycling, and he joined their Olympic Development Programme in November 2006 and won the junior version of Paris–Roubaix in 2008, before moving on to the Olympic Academy Programme in 2009-2010.
At the 2010 Commonwealth Games, Fenn – who was qualified to ride for Scotland as his mother was Scottish-born – finished 14th in the men's road time trial.
His first year riding as a professional was in 2011, in which he claimed two victories and the bronze medal in the under-23 road race at the Road World Championships.
In September 2014, it was announced that Fenn had signed for Team Sky, joining on 1 January 2015.
