Stellingwarfs (nl|Stellingwerfs) is a Westphalian and Friso-Saxon dialect spoken in Ooststellingwerf and Weststellingwerf in the Dutch province of Friesland, and also in Steenwijkerland and Westerveld in the Dutch province of Overijssel and Drenthe.
Like Het Bildt and Leeuwarden, Weststellingwerf and Ooststellingwerf are among the municipalities of Friesland where West Frisian is not spoken.
The language was identified by the government of the Netherlands in 1996 within Low Saxon.
