Bokmål (UK: literally "book tongue") is an official written standard for the Norwegian language, alongside Nynorsk. Bokmål is the preferred written standard of Norwegian for 85% to 90% of the population in Norway. Unlike, for instance, the Italian language, there is no nationwide standard or agreement on the pronunciation of Bokmål.

Bokmål is regulated by the governmental Language Council of Norway. A more conservative orthographic standard, commonly known as Riksmål, is regulated by the non-governmental Norwegian Academy for Language and Literature. The written standard is a Norwegianised variety of the Danish language.
