The Ohrekreis was a district (Kreis) in the north-east of Saxony-Anhalt, Germany.

Neighboring districts are (from north clockwise) Altmarkkreis Salzwedel, Stendal, Jerichower Land, the district-free city Magdeburg, Bördekreis, and the districts Helmstedt and Gifhorn in Lower Saxony.

Except two changes in 1908 when the municipality Rothensee became part of Magdeburg, and in 1944 when Calvörde became part of Haldensleben the districts did not change until a bigger reform in 1952.

The district is located on the plain called Magdeburg Börde (in the south), the Drömling (in the northwest) and the Colbitz-Letzlingen Heath (in the northeast), and named after the river Ohre which flows parallel to the canal Mittelland Canal.

The wavy line in the bottomright symbolizes the river Ohre, after which the district is named.
