Jamaica is an island nation of the Greater Antilles roughly 240 kilometres (150 mi) in length and as much as 85 kilometres (50 mi) in width. It is 635 kilometres (391 mi) east of the Central American mainland, 150 kilometres (93 mi) south of Cuba, and 180 kilometres (112 mi) west of the island of the Dominican Republic are situated. It is the third most populous Anglophone country in the Americas, after the United States and Canada. Jamaica is the largest English speaking island in the Caribbean.

Jamaica is the third largest island in the Caribbean. The island of Jamaica is home to the Blue Mountains inland and is surrounded by a narrow coastal plain. For this reason, most major towns and both cities are located on the coast. Chief towns include the capital city Kingston, Spanish Town, Mandeville, Ocho Rios, Port Antonio and the city of Montego Bay.

The climate in Jamaica is tropical, with hot and humid weather, although inland regions have a more temperate climate. Some regions on the south coast, such as the Liguanea Plain and the Pedro Plains are relatively dry rain-shadow areas.
