Richard Virenque (born 19 November 1969) is a retired French professional road racing cyclist. He was one of the most popular French riders with fans for his boyish personality and his long, lone attacks. He was a climber, best remembered for winning the King of the Mountains competition of the Tour de France a record seven times, but he is best known from the general French public as one of the central figures in a widespread doping scandal in 1998, the Festina Affair, and for repeatedly denying his involvement despite damning evidence.

He turned professional for RMO in January 1991. Virenque rode his first Tour de France in 1992 as a replacement for another team member, Jean-Philippe Dojwa. He was earning 15,000 francs a month. He said he dreamed only of "being able to follow the best in the mountains, riders like Claudio Chiappucci, Indurain, LeMond, Thierry Claveyrolat." On the third day he took the yellow jersey as leader of the general classification after a long breakaway with two other riders on the col de Marie-Blanque in the Pyrenees. He held it for a day, losing it next day to his team-mate Pascal Lino, who led for the next two weeks. Virenque finished second in the climbers' competition.

Virenque was sought by several teams after his first Tour and Cyrille Guimard said at the world championship at Benidorm that he had arranged for him to join his Castorama team, where he would replace Laurent Fignon. But the announcement was premature and Virenque joined another French team, Festina. He stayed there until the team dissolved in the wake of a doping scandal in 1998 (see below).

Virenque first wore the yellow jersey of the Tour de France in 1992 and for the last time in 2003. In 2003 he won the stage to Morzine and wore the jersey on the climb of Alpe d'Huez. Virenque was a talented climber but a modest time-triallist. He was coached for time-trials by Jeannie Longo and her husband.

Virenque finished twice on the podium in the Tour de France (third in 1996 and second in 1997) and won several stages, among them Mont Ventoux in 2002. He is the 18th rider in the Tour to have won stages over 10 years apart; he wore the Maillot Jaune for two days in his entire career.
