The Ayau Islands (Kepulauan Ayau), are a small archipelago south of the Asia Islands and north of Waigeo Island (in the Raja Ampat Islands) in Indonesia; they are separated from Waigeo Island by the Bougainville Strait. This group is formed by two coral atolls. The highest point is 106 m.^[1]

In older maps these islands appear as the Ajoe Islands, following the Dutch spelling "Ajoe-eilanden".

The beaches of these islands are a breeding ground for the leatherback turtle (Dermochelys coriacea). The waters off the Ayau Islands are a good snorkeling and scuba diving site.

Administratively the Ayau Islands belong to the Indonesian province of Southwest Papua, and form part of the Raja Ampat Regency.
