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.

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.
