Les Ardentes is a Belgian multi-day electro-rock music festival which yearly takes place in Liège, in early July. The last edition of the event took place in the district of Rocourt. Les Ardentes is organised ever since 2006, with Fabrice Lamproie and Gaëtan Servais as founders. The festival name is a French plural noun meaning "The Burning", a referral to the nickname of host city Liège, La cité ardente ("The Burning City").
