Vilhonneur (French pronunciation: [vilɔnœʁ]; Occitan: Vilonor) is a former commune in the Charente department in southwestern France.

The present castle was built by the Chambes (aka Jambes) family in the late sixteenth century.

The Placard cave, at Rochebertier, was discovered in 1853 and has been dated to the Magdalenian and Solutrean periods.

It contains engravings as well as human and animal bones dating from the Upper Paleolithic period (around 25 000 years BCE).

At the site of the old Roman ford there is still the 50 cm-wide stone bridge, which was characteristic of the Tardoire and Bandiat valleys.
