Guyana officially the Co-operative Republic of Guyana, is a sovereign state on the northern mainland of South America. It is, however, included in the Caribbean Region due to its strong cultural, historical, and political ties with other Anglo Caribbean countries and the Caribbean Community (CARICOM).

With 215,000 square kilometres (83,000 sq mi), Guyana is the fourth-smallest country on mainland South America after Uruguay, Suriname and French Guiana (an overseas region of France).
