The Tour de Luxembourg is an annual stage race in professional road bicycle racing held in Luxembourg. The Tour de Luxembourg is classified as a 2.Pro race, the highest rating below the World Tour, by the Union Cycliste Internationale (UCI), the sport's governing body.
In 2006, the Tour became part of the UCI Europe Tour, and became part of the UCI ProSeries in 2020. Primarily held in late May to early June, the event was sometimes used by riders as a preparation race for the Tour de France.
