Ereikoussa (Greek: Ερείκουσα) is an island and a former community of the Ionian Islands, Greece. Since the 2011 local government reform it is part of the municipality Corfu, of which it is a municipal unit. It is located off the northwestern coast of the island of Corfu, and is almost equidistant from Corfu to the southeast, Mathraki to the southwest, and Othonoi to the west. There is only one town on the island, also named Ereikoússa. Its population was 698 at the 2001 census and its land area is 3.7 square kilometres (1 sq mi). The island is rich in green forests, filled with cypress, and olive trees. It has two beaches, Porto (Πόρτο) and Braghini (Μπραγκίνι), which are two Italian originated names that were named during Venetian rule. Though Braghini is rarely used it is known to be nicer then the other beach Porto. Bragini is not used very much due to the fact that it is further away from the main part of the island.
The two primary ways to get to Erikoussa is through a boat called Sea Away that leaves from Sidari, a city in northern Corfu, or the Alexandros, a boat that leaves from Corfu Town. The Sea Away boat takes about 40 min. while the Alexandros takes about 2 hours 45 min.
