La Flèche Wallonne is a men's professional cycle road race held in April each year in Wallonia, Belgium. The first of two Belgian Ardennes classics, La Flèche Wallonne is today normally held mid-week between the Amstel Gold Race and Liège–Bastogne–Liège.
Since 1998 the women's race is held. The Flèche Wallonne Féminine is held in conjunction with the men's race, on much of the same roads but at a shorter distance. It is part of the UCI Women's World Tour and it is the third-oldest single-day event after the Trofeo Alfredo Binda in Italy and the Emakumeen Euskal Bira in the Basque Country.
