Icaria, also spelled Ikaria, is a Greek island in the Aegean Sea, 10 nautical miles (19 km) southwest of Samos. According to tradition, it derives its name from Icarus, the son of Daedalus in Greek mythology, who was believed to have fallen into the sea nearby.

Administratively, Icaria forms a separate municipality within the Ikaria regional unit, which is part of the North Aegean region. The principal town of the island and seat of the municipality is Agios Kirykos. The historic capitals of the island include Oenoe and Evdilos.

Icaria has a tradition of producing strong red wine. Many parts of the island, especially the ravines, are covered in shrubbery, making the landscape lush with green. Aside from domestic and domesticated species such as goats, there are a number of small wild animals to be found, such as martens, European otters, jumping spiders, and green toads. Icaria exhibits a typical Mediterranean climate.
