Pessegueiro Island is a volcanic islet in the parish of Porto Covo, located off the southwest coast of Portugal. The island is part of Portugal's Southwest Alentejo and Vicentine Coast Natural Park. The island is very small and currently unihabited. The name Pessequiro translates as "peach tree," though it is thought that it is derived from the name of a fish factory (piscatorius) that used to be on the island.

Many birds use the cliffs of the island as a stopover and hatchery including the white stork, Bonelli’s eagle and carrion crows. Pessegueiro Island hosts various ruins, including the 600-year old Portuguese fort, Forte de Santo Alberto, along with even older Carthaginian and Roman ruins. The islands were first occupied by the Carthaginians as far back as 218 B.C.E.
