Isla de Ratones (English: Mice Island) is a small uninhabited island off the southern coast of Puerto Rico, off the coast of Ponce. The island is part of barrio Canas in the municipality of Ponce. The island gained attention in 2010 when the Puerto Rican Bird Society made it a target for the eradication of the black rat. While named as one single island, it is actually composed of two islands separated by a few feet of shallow water during high tide, which become a single island at low tide.
