The von Plotho family are a German noble family traditionally believed to be of Wendish origin, particularly associated with the Prignitz region in Brandenburg. The family is documented as early as 946 in a writ of Otto the Great as already in possession of their ancient seat at Burg Plote in Altenplathow, Elb-Havelland in Brandenburg. Their line of recorded continuous descent dates the 12th century, with Hermann I von Plotho.Their extensive possessions, from the 11th and 12th centuries, centred on the old Prignitz region and included Kyritz, Wusterhausen and Genthin, the territory of Schollene, the castle at Plote (Altenplathow), the Gaue of Lietzici, Zemzizi and Drenzile, and the lordship of Parey. They were also closely associated with the Bishops of Magdeburg: Hermann I, whose Romanesque monumental effigy is still to be seen in the church of Altenplathow was a vassal of the bishops and other members of the family were canons of Magdeburg Cathedral. Their vassals included the von Blumenthal family, whom they brought from Blumenthal in the diocese of Magdeburg to Blumenthal in the Prignitz.
