Chaillevois (French pronunciation: [ʃajvwa]) is a commune in the Aisne department in Hauts-de-France in northern France.

The river Ailette forms part of the commune's southern border.

The name of this village seems derive from an old path that probably happened in this place, callis via, or royal road.

The village once belonged to the bishops of Aaon, who lost possession in the French Revolution.

It was also the home town of Jean-Baptiste Tholmé, a general in the time of the Revolution.
