Mona (Spanish: Isla de la Mona) is the third-largest island of the archipelago of Puerto Rico, after the main island of Puerto Rico and Vieques. It is the largest of three islands located in the Mona Passage, a strait between the Dominican Republic and Puerto Rico, the others being Monito Island and Desecheo Island. It measures about 11 km by 7 km (7 miles by 4 miles), and lies 66 km (41 mi) west of Puerto Rico, of which it is administratively a part. The original name given to the island by the Taíno Indians is Amona, which means "what is in the middle", referring to the journey between the islands of Puerto Rico and Hispaniola. It is one of two islands that make up the Isla de Mona e Islote Monito Barrio of Mayagüez, Puerto Rico.

The island is a natural reserve and, though there are no native inhabitants, rangers from the island's Department of Natural and Environmental Resources reside on the island to manage visitors and take part in research projects.
