Autremencourt (French pronunciation: [otʁəmɑ̃kuʁ]) is a commune in the department of Aisne in the Hauts-de-France region of northern France.

It can be accessed by the D64 road from La Neuville-Bosmont in the east passing through the heart of the commune and the village and continuing west to Toulis-et-Attencourt.

[3] Shards of pottery, Roman tiles, and medals bearing the image of the emperors have been discovered in the locality of Jardins de Certeau in the territory of Autremencourt but the name of the locality (Ostremoncourt) is mentioned for the first time in 1018 in an Adalberon charter and it was in the 12th century that the first lord of the manor, Renaud de Bidane appeared.

The lords of the region often operated on the battlefield (Stoppa, for example), while Beat de Saxer occupied his lordship during the revolutionary period.

From the 18th century, the archives are more detailed on the daily lives in Autremencourt; on properties, businesses, housing, lawsuits and various facts.
