Aubenton derives its name from its location near the confluence (in the commune of Hannappes to the east) of the Aube (Thon) and the Thon.
The commune is located some 70 km east of Saint Quentin and 40 km west by north-west of Charleville-Mezieres. The D1043 (E44) road from Hirson to Charleville-Mezieres runs along the northern border of the commune. The village can be accessed from this road by the D5 road running south-east or the D37 road running south-west. The D5 road continues through the commune and south, changing to the D977, and continuing to Rozoy-sur-Serre. The D37 road continues west from the village to Besmont. There is also the D38 road from Leuze in the west passing through the village and continuing to Hannappes in the east. The railway from Hirson to Charleville-Mezieres also passes through the commune following the course of the Thon river but there is no station in the commune - the nearest being at Liart to the east. The commune is about 80% farmland with the rest extensive forests in the south. There are a number of hamlets other than the village. These are:
Bas Val La Caure
Haute Val la Caure
La Rue Larcher
Le Bois Carbonnet
The Thon River flows from east to west through the north of the commune eventually joining the Oise river at Etreaupont. The Ruisseau de Bois Carbonnet rises in the south of the commune and flows west then north joining other tributaries then the Ton river.

Shot by the Gestapo on the Aubenton-Besmont road (D37) on 30 March 1944, Emile Fontaine was recognized as a captain in the French Forces of the Interior (FFI) after the Liberation. All three had saved 10 escapees from the "Judenlager of Mazures" who hid for a time at Buirefontaine.
In 2010, the commune had 713 inhabitants. The evolution of the number of inhabitants is known through the population censuses conducted in the town since 1793. From the 21st century, a census of municipalities with fewer than 10,000 inhabitants is held every five years, unlike larger towns that have a sample survey every year.[Note 1][Note 2]

^At the beginning of the 21st century, the methods of identification have been modified by law No. 2002-276 of 27 February 2002 , the so-called "law of local democracy" and in particular Title V "census operations" which allow, after a transitional period running from 2004 to 2008, the annual publication of the legal population of the different French administrative districts. For municipalities with a population greater than 10,000 inhabitants, a sample survey is conducted annually, the entire territory of these municipalities is taken into account at the end of the period of five years. The first "legal population" after 1999 under this new law came into force in 1 January 2009 and was based on the census of 2006.
^In the census table and the graph, by convention in Wikipedia, and to allow a fair comparison between five yearly censuses, the principle has been retained for subsequent legal populations since 1999 displayed in the census table and the graph that shows populations for the years 2006, 2011, 2016, etc., as well as the latest legal population published by INSEE
