Herbeumont (French pronunciation: [ɛʁbømɔ̃]; Walloon: Arbûmont) is a municipality of Wallonia located in the province of Luxembourg, Belgium.

The municipality consists of the following districts: Herbeumont, Saint-Médard, and Straimont.

Other population centers include: Gribomont, Martilly, and Menugoutte.

In April 1998 Marc Dutroux escaped from his guards while being transferred to court without handcuffs by overpowering one of his guards and taking his pistol, but was captured later in Herbeumont by a ranger in the nearby woods.

This resulted in the resignation of minister of interior Johan Vande Lanotte, minister of justice Stefaan De Clerck and the former police chief.
