The Lordship (or Principality) of Parchim-Richenberg (German: (Fürstentum) Herrschaft Parchim-Richenberg) was a short-lived state of the Holy Roman Empire which existed during the 13th century. It arose from the first partition of Mecklenburg after the death of Henry Borwin II, Lord of Mecklenburg in 1226. Initially it was named after its capital Parchim. Later, following the transferral of the seat to Richenberg, the name shifted to Richenberg. The Lordship comprised the lands of Parchim (included Brenz and Rosengarten), the rural area of Ture and the later Vogteis of Plau, Goldberg, Sternberg and finally Richenberg (on the Warnow near Langen Brütz). It was the shortest-lived of the four partitioned principalities of Mecklenburg.
