The coat of arms show the eagle of Brandenburg to the left, as the margraves of Brandenburg began to rule the northern and northwestern part of the district in the 13th century. To the right is a staff of an abbot. It symbolizes the clerical state of Magdeburg, to which the southern and middle part of the district belonged. The black-and-white checkered bottom derives from the coat of arms of the family of Torgow, who owned the area around Zossen until 1478.
After the creation of the new district a public contest was held to create a coat of arms for the district. Out of ten proposals the parliament of the district selected the one made by the designer Horst Nehls from Merow. The coat of arms were officially granted by ministry of interior of Brandenburg on November 21, 1996.
