That depends on your source of reference. Wikipedia has the following:

North America is often divided into subregions but no universally accepted divisions exist. "Central America" comprises the southern portion of the continent, but its northern terminus varies between sources. The United Nations includes Mexico in Central America, while most other definitions of the region do not (e.g., the European Union excludes Belize and Mexico from the area). The term Middle America is sometimes used to refer to Mexico, Central America, and the Caribbean collectively.

Northern America is used to refer to the northern countries and territories of North America: Canada, the United States, Greenland, Bermuda, and St. Pierre and Miquelon. They are often considered distinct from the southern portion of the Americas, which largely comprise Latin America.

The Caribbean refers to the islands in and around the Caribbean Sea and the surrounding coasts.
