Oinousses (Greek: Οινούσσες, alternative forms: Aignousa (Αιγνούσα) or Egnousa (Εγνούσα)) is a barren cluster of 1 larger and 8 smaller islands some 2 kilometres (1 mile) off the north-east coast of the Greek island of Chios and 8 km (5 miles) west of Turkey.

The principal town of the islands and seat of the municipality is also called Oinousses.

The vast majority of the workforce of the island is engaged in seafaring, fishing and goat-herding.

The islands are noted as the origin of an unusual cluster of successful ship-owning families: the Lemos, Pateras, Hadjipateras, Samonas,Kollakis and Lyras families.

Whilst most of the families now live elsewhere most of the year, the islands and town are well maintained with a strong naval connection.
