Icaria, also spelled Ikaria (Greek: Ικαρία), locally Nikaria or Nicaria (Νικαριά), previous name: Doliche (Δολίχη), is a Greek island 10 nautical miles (19 km) south-west of Samos. It derived its name from Icarus, the son of Daedalus in Greek mythology, who fell into the sea nearby. It is one of the middle islands of the northern Aegean, 660 km² (255 mi²) in area with 102 miles (160 km) in coastline and a population of about 7,000 inhabitants. The topography is a contrast between verdant slopes and barren steep rocks.

The island is mountainous for the most part. It is traversed by Aetheras range, whose highest summit is 1,040 metres. Most of its villages are nestled in the plains near the coast, with only some of them on the mountains. Icaria has a tradition in the production of strong red wine. Many parts of the island are covered by large bushes, especially ravines, making the landscape lush with green. There are no rare species of fauna on the island. Besides pets, only small goat herds make their presence known, disturbing the serenity of the island with their bells. Icaria's climate is considered mild.
