The Saalhausen Hills (German: Saalhauser Berge) are a range of hills up to 687.7 m above sea level (NN) high in the Sauerland region within the districts of Olpe and Hochsauerlandkreis in the German state of North Rhine-Westphalia.

The hills are named after the village of Saalhausen, part of the town of Lennestadt, which is located on the southern edge of this forested region.

The hills are clearly delineated in the south by the Lenne and cover that part of the Sauerland between Lennestadt in the west and Schmallenberg in the east.

The hills, whose southwest and central areas fall within the Rothaargebirge Nature Park, are located north of the upper Lenne valley, southeast of the Elspebach and southwest of the upper course of the Wenne.

A section of the Homert Trail runs through the Saalhausen Hills over a pass between the Himberg and Hoher Lehnberg.
