El Tigre is an island located in the Gulf of Fonseca, a body of water on the Pacific coast of Central America. The island is a conical basaltic stratovolcano and the southernmost volcano in Honduras. It belongs to Valle department. Together Isla Zacate Grande, Isla Comandante and a few tiny satellite islets and rocks, it forms the municipality of Amapala, with an area of 75.2 km² and a population of 9,687 as of the census of 2001 (of which 4 people were living on Isla Comandante).

Three countries, Honduras, El Salvador, and Nicaragua, have coastline along the Gulf of Fonseca, and all three have been involved in a lengthy dispute over the rights to the gulf and the islands located there within. In 1992, a chamber of the International Court of Justice (ICJ) decided the Land, Island and Maritime Frontier Dispute, of which the gulf dispute was a part. The ICJ determined that El Salvador, Honduras, and Nicaragua were to share control of the Gulf of Fonseca. El Salvador was awarded the islands of Meanguera and Meanguerita, and Honduras was awarded the island of El Tigre.
