The Hochthürmerberg is located within the Ahr Hills (Ahr Eifel) south of the village of Houverath in the county of Euskirchen ni North Rhine-Westphalia and northeast of the village of Kirchsahr in the county of Ahrweiler in Rhineland-Palatinate. The state border runs roughly along the 440-metre contour line over the southern flank of the hill. The Hochthürmerberg's neighbouring hill is the Hasenberg.
