Pierre Ballester (1959) is a French sports journalist. He has written extensively about doping in cycling.
He was a correspondent in London for Agence France-Presse, Sport, and L'Equipe.
Ballester co-wrote L.A. Confidentiel with David Walsh. It was published in 2004 by La Martinière. The book resulted in a number of lawsuits by Lance Armstrong's lawyers in France and England.
He also co-wrote Le Sale Tour (a pun in French : literally « the dirty tour », for Tour de France, double entending « dirty trick [also 'tour' in french] » ) with Walsh, about Armstrong's "comeback" in the 2009-2010 period.
