Asserbo Charterhouse was a short-lived Carthusian monastery, or charterhouse, at Asserbo north of Roskilde on the island of Zeeland in Denmark.
While Eskil, archbishop of Lund, was in exile in France he came into contact in 1156 with the Carthusians, either at the Grande Chartreuse or at Mont-Dieu Charterhouse, and was inspired to attempt a Carthusian foundation in Denmark.
Asserbo Charterhouse, in his diocese, was the result, and appears to have been founded in 1163, although there is evidence of a Carthusian presence there from 1162. The site however proved unsuitable, and the monastery was abandoned in 1169.
