English is the official language of Guyana, which is the only South American country with English as the official language.

Guyanese Creole (an English-based creole) is widely spoken in Guyana.

Guyanese Hindustani is retained and spoken by some Indo-Guyanese for cultural and religious reasons. Guyanese Bhojpuri may be used by older generations, folk songs, or in a limited way at home, while standard Hindi is used in religious service, writing, and passively through the consumption of Hindi film exports from India. Tamil was once spoken by a segment of the Indo-Guyanese community, although its usage has declined over generations, and it remains mostly in religious and cultural contexts.

A number of Amerindian languages are also spoken by a minority of the population. These include Cariban languages such as Macushi, Akawaio and Wai-Wai; and Arawakan languages such as Arawak (or Lokono) and Wapishana.
