The official language of Greenland is Greenlandic. The number of speakers of Greenlandic is estimated at 50,000, divided in three main dialects, Kalaallisut, Tunumiit and Inuktun. The remainder of the population mainly speaks Danish; Greenlandic Sign Language is the language of the deaf community.

Danish is a North Germanic language spoken by about six million people, principally in Denmark, Greenland, the Faroe Islands and in the region of Southern Schleswig in northern Germany, where it has minority language status. Also, minor Danish-speaking communities are found in Norway, Sweden, Spain, the United States, Canada, Brazil, and Argentina. Due to immigration and language shift in urban areas, about 15–20% of the population of Greenland speak Danish as their first language.

Greenlandic is an Eskimo–Aleut language with about 56,000 speakers, mostly Greenlandic Inuit in Greenland. It is closely related to the Inuit languages in Canada such as Inuktitut. It is the most widely spoken Eskimo-Aleut language.

The Inuit languages are a closely related group of indigenous American languages traditionally spoken across the North American Arctic and to some extent in the subarctic in Labrador. The related Yupik languages are spoken in western and southern Alaska and in the far east of Russia, but are severely endangered in Russia today and spoken only in a few villages on the Chukchi Peninsula. The Inuit live primarily in three countries: Greenland, Canada, and the United States.

Inuktun is the language of approximately 1,000 indigenous Inughuit, inhabiting the world's northernmost settlements in Qaanaaq and the surrounding villages in northwestern Greenland.

Tunumiit oraasiat or East Greenlandic is a variety of Greenlandic spoken in eastern Greenland by the Tunumiit. It is generally considered a divergent dialect of Greenlandic, but verges on being a distinct language. The largest town where it is the primary language is Tasiilaq on Ammassalik Island, with the island's name being derived from the West Greenlandic name of the town.

West Greenlandic, also known as Kalaallisut, is the standard dialect of the Greenlandic language, spoken by the vast majority of the inhabitants of Greenland, as well as by thousands of Greenlandic Inuit in Denmark proper. It was historically spoken in the southwestern part of Greenland, i.e. the region around Nuuk.
