Kamenz (Sorbian languages: Kamjenc, pronounced [ˈkamʲɛnts]) was a Kreis (district) in the north-east of Saxony, Germany.

Neighboring districts were (from north clockwise) Oberspreewald-Lausitz, Spree-Neiße, Niederschlesischer Oberlausitzkreis, Bautzen - Budyšin, Sächsische Schweiz, the district-free city Dresden - Drježdźany, and the districts Meißen and Riesa-Großenhain.

The district-free city Hoyerswerda was surrounded by the district.

From 1994 to 1996 it was called Westlausitz - Dresdner Land, but then renamed to Kamenz again.

The two major rivers in the district were the Spree and the Schwarze Elster (Black Elster).
