Awaous guamensis is a species of goby native to the Pacific islands from the Marianas to Vanuatu, New Caledonia and Fiji where it can be found in fresh, brackish and marine waters. Recent work based upon morphological and genetic differences has recognized Hawaiian populations of Awaous as being distinct from Awaous guamensis. Consequently, Hawaiian Awaous are now recognized as a distinct species Awaous stamineus.
