Abbenrode is a village and a former municipality in the district of Harz, in Saxony-Anhalt, Germany. Since 1 January 2010, it has been part of the municipality of Nordharz. The village is situated north of the Harz mountain range, near the Ecker creek and the border with the state of Lower Saxony. The Abbenrode manor, possibly named after a first settler called Abbo, arose in the medieval Duchy of Saxony and was first mentioned as Abbenrot in an 1129 deed issued by King Lothair III of Germany.
