Florennes (French pronunciation: [flɔ.ʁɛn]; Walloon: Florene) is a municipality of Wallonia located in the province of Namur, Belgium.

The municipality consists of the following districts: Corenne, Flavion, Florennes, Hanzinelle, Hanzinne, Hemptinne, Morialmé, Morville, Rosée, Saint-Aubin and Thy-le-Bauduin.

Florennes hosts Florennes Air Base, a Belgian military airfield which is the home base for F-16 Fighting Falcon jets.

The first week-end of every July, Florennes is a large festival due to the folk walk with a couple of thousand valorous walkers.

The village was formerly the site of Florennes Abbey, dissolved during the French Revolution and since entirely demolished.
