Beaumé is located some 70 km east of Saint-Quentin and 50 km west of Charleville-Mézières. It can be accessed by the D37 road from Besmont in the west passing through the commune and the village and continuing east to Aubenton. There are also several other country roads accessing the commune from all directions. Apart from the village there are two other hamlets: La Courte Soupe and Monplaisir. The south of the commune is heavily forested however most of the commune is farmland.[3]
The Ruisseau de l'Etang Polliart flows from the southeast of the commune to the north with several tributaries as it continues north out of the commune to join the Ton river at Leuze.[3]
