Halberstadt was a district (Kreis) in the middle of Saxony-Anhalt, Germany.

Neighboring districts were (from north clockwise) Bördekreis, Quedlinburg, Wernigerode, Goslar, Wolfenbüttel, Helmstedt.

During the Napoleonic Wars it became part of the French-controlled Kingdom of Westphalia, where Halberstadt was the capital of the Département of the Saale.

In 1815 it came back to the Kingdom of Prussia, and in 1816 it became part of the Regierungsbezirk Magdeburg within the newly established Prussian Province of Saxony.

The district is located at the northern end of the Harz mountains.
