Klein Bonaire is a small uninhabited islet off the west coast of Bonaire, part of the Dutch special municipality of Bonaire. It is extremely flat, rising no more than two meters above the sea. The Bonaire National Marine Park covers the waters around it, with coral reefs and shallow lagoons.

The islet has no buildings beyond some ruins of slave huts and a small open shelter on the beach facing Bonaire. Green and hawksbill sea turtles live here permanently, and the islet is also an Important Bird Area for threatened species such as bare-eyed pigeons and least terns. Visitors come by boat for the water and the beach.

• Do not swim alone at the remote park beaches. The park is remote, so go with someone.
• Visitors going by water taxi must buy a nature tag.
• Marine park rules ban gloves, chemical glow sticks and spearfishing. Booties are recommended for rough shore entry.
• The islet has no running water or sanitation, so bring water and plan for the day.
