Stegastes punctatus, commonly known as the blunt snout gregory, is a damselfish of the family Pomacentridae.

It is native to the Indo-Pacific region where it is found at depths down to 5 m (16 ft).

Its range extends from the East African coast and the Red Sea to the Line Islands, the Society Islands, the Ryukyu Islands, the Bonin Islands, New Caledonia, Tonga and Micronesia.

[2] It is a very territorial species and drives other fish away from its "garden" of filamentous algae.
