The Árni Magnússon Institute for Icelandic Studies is an institute of the Ministry of Education, Science and Culture of Iceland which conducts research in Icelandic and related academic studies, in particular the Icelandic language and Icelandic literature, to disseminate knowledge in those areas, and to protect and develop the collections that it possesses or those placed in its care. It is named after Árni Magnússon, a 17th–18th century collector of medieval Icelandic manuscripts.

Icelandic is a North Germanic language from the Indo-European language family spoken by about 314,000 people, the vast majority of whom live in Iceland, where it is the national language. Since it is a West Scandinavian language, it is most closely related to Faroese, western Norwegian dialects, and the extinct language Norn. It is not mutually intelligible with the continental Scandinavian languages and is more distinct from the most widely spoken Germanic languages, English and German. The written forms of Icelandic and Faroese are very similar, but their spoken forms are not mutually intelligible.
