Goslar is a district in Lower Saxony, Germany. It is bounded by (from the south and clockwise) the districts of Göttingen, Northeim, Hildesheim and Wolfenbüttel, the city of Salzgitter, and by the states of Saxony-Anhalt (district of Harz) and Thuringia (Nordhausen).

The history of the district is linked with the city of Goslar.

The district of Goslar was established in the 19th century by the Prussian government. The city of Goslar did not belong to the district until 1972, when it was eventually incorporated into the district.

The region comprises the northwestern part of the Harz mountains. The Harz National Park is part of this district. The highest peak is the Wurmberg (971 m) near Braunlage, also being the highest elevation of Lower Saxony. Above the small town of Altenau there is the source of the Oker river, which runs through the picturesque Oker valley to leave the Harz at Vienenburg.
