Cuba is an island nation, so its boundaries are defined by the waters surrounding it:

* North: The Straits of Florida, which separate Cuba from the United States (Florida).

* East: The Atlantic Ocean.

* South: The Caribbean Sea.

* West: The Yucatan Channel, which separates Cuba from Mexico (Yucatan Peninsula).

Cuba also includes a few smaller islands nearby, such as the Isle of Youth (Isla de la Juventud).
