Friesland (Fryslân in West Frisian, Friesland in Dutch) is a province in the north of the Netherlands. The capital (city) of Friesland is Leeuwarden (Ljouwert in Frisian). People in Friesland speak West Frisian and Dutch. People also speak Frisian in a small part of Groningen (province), and in East Friesland and North Friesland in Germany. In North Holland there is a region called West Friesland, but people who live there are not called Frisians. About 651,000 people are living in Friesland (2021).

Agriculture and tourism, on the lakes and the isles in the Wadden Sea, are important sources of income.

The province is also famous for its ice skaters and its Elfstedentocht (Eleven cities tour), an ice skating race of 200 kilometers.

It is also known for being home to some breeds of animals, such as the Stabyhoun and Wetterhoun dog breeds, the Friesian horse breed and the Holstein Friesian cattle breed.
