The Brilon Plateau (German: Briloner Hochfläche) is a highland area in the county of Hochsauerlandkreis in the German state of North Rhine-Westphalia. It is surrounded by the Brilon Heights (Briloner Höhen), whose mountains reach a height of 670.2 m above sea level (NHN).

The countryside of the Brilon Plateau and Brilon Heights includes the town of Brilon itself and several of its municipalities. Administratively it belongs largely to Hochsauerlandkreis, in the northeast, near Bleiwäsche, it is part of the county of Paderborn. It is roughly elliptical in shape; its longitudinal axis running from east-northeast to west-southwest.

To the north and northeast it transitions via the Alme Uplands into the Sintfeld. In the east and southeast it descends into the very deeply incised valley of the Hoppecke. In the south it is adjoined by the Sauerland and Upland (landscapes in the Rothaar Mountains); in the west by the Warstein Forest (the eastern part of the Arnsberg Forest Nature Park) and in the northwest by the narrow Haarstrang. In the north the terrain descends (on the far side of Sintfeld and Haarstrang) more or less gently into the Westphalian Bight towards the River Lippe. The plateau forms an island of farmland in the middle of forested mountains and hills.

• Borberg (670.2 m) – southwest of Brilon
