Fabien Lefèvre (born 18 June 1982)[1] is a French slalom canoeist who has competed at the international level since 1998.

At the 2005 World Championships in Penrith, New South Wales he won a silver medal in the K1 event, losing only to Fabian Dörfler.

He finished 5th in the individual event in 2006 in a race where two winners were declared by the ICF jury (Julien Billaut and Stefano Cipressi).

In 2007 a serious wrist injury prevented him from taking part at the World Championships in Foz do Iguaçu, won by his compatriot Sébastien Combot.

Benjamin Boukpeti, a friend of Lefèvre, won the first Olympic medal for Togo with a bronze, while Alexander Grimm took gold.

In late 2008, inspired by Michael Phelps, he decided to take up the double canoe discipline (C2) together with Denis Gargaud Chanut, while continuing to race in single kayak (K1) with the ambition to appear in both categories at the 2012 Summer Olympics.

Nonetheless, after 2012, Fabien moved to the United States and began competing as an American Canoe Slalom Athlete.
