Kamenz (Sorbian: Kamjenc) is a Landkreis (rural district) in the north-east of the Free State of Saxony, Germany. The independent city Hoyerswerda is completely surrounded by the district. They will be a reorganisation of districts in Saxony in July 2008, and Hoyerswerda will become a part of Landkreis Kamenz instead of having a separate government.
The district was formed in 1994 from the previous Kamenz district, the northern parts of the Dresden-Land district, around Radeberg, and the Hoyerswerda district, except the town of Hoyerswerda, which became a district-free city. From 1994 to 1996 it was called Westlausitz - Dresdner Land, but then renamed to Kamenz again.
The colours of the coat of arms are those of the Upper Lusatia. The black wing on the right side is the symbol of the Lords (German: Herr) of Kamenz. The linden leaf in the top of the left half stands for the Sorbian minority. The wavy line below symbolizes the three rivers Röder, Elster and Spree. The three rings in the bottom symbolize the joining together of the three old districts. The symbol was taken from the play "Nathan der Weise" by Lessing.
