Nakhiloo Island (also: Nakhilo, Nakhilu, Nokhailo; Persian: جزیره نخیلو, jazireye Nakhiloo ) is one of the Iranian islands in the Persian Gulf.

The island is located southeast of Bushehr.

Nakhiloo, along with neighbouring Morghu and Ummal Karam islands, has been designated an Important Bird Area (IBA) by BirdLife International because they support breeding crab-plovers as well as colonies of bridled, Saunders's, lesser crested and white-cheeked terns.

The islands are also a breeding site for hawksbill sea turtles.
