Glossodoris cincta is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae.

This name has been extensively used for a group of similarly coloured species, some of which are unnamed.

[2] This species was described from Ile Marianne, Fouquets Reef, Mauritius.

This species has been reported in error widely in the Indo-Pacific region but these reports should be referred to Glossodoris acosti or undescribed Glossodoris species.

[3] Glossodoris cincta has a mantle which is tawny brown with blue-white dots and a dark blue margin to the mantle which is separated from the brown by a thin grey line.
