The SSS islands (Dutch: SSS-eilanden), locally also known as the Windward Islands (Bovenwindse Eilanden or Bovenwinden), is a collective term for the three territories of the Dutch Caribbean (formerly the Netherlands Antilles) that are located within the Leeward Islands group of the Lesser Antilles in the Caribbean Sea.

In some contexts, the term is also used to refer to the entire island of Saint Martin (which also includes the Collectivity of Saint Martin), alongside Sint Eustatius and Saba.

Since then, Sint Maarten is a constituent country of the Kingdom of the Netherlands, while Sint Eustatius and Saba are special municipalities of the Netherlands.

"SSS" is an acronym of the islands' names, and is analogous to the ABC, CAS, and BES islands, which are other commonly used subdivisions of the Dutch Caribbean.

The island of Saint Martin was split between France and the Netherlands in 1648.
