Märkisch-Oderland is a Landkreis (district) in the eastern part of Brandenburg, Germany.

The district extends from the outskirts of Berlin in the west to the Oder river and the Polish border in the east.

In 1993 the three parts were merged to form the current district - the new name refers to Northmarch lands at the Oder river.

The upper half also resembles the coat of arms of the former district of Oberbarnim.

In the lower half are two boat-hooks and a star, both taken from the coat of arms of the former district of Seelow.
