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 un-named.
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. The rhinophores are dark brown with blue-white dots. The living holotype was 60 mm (2.4 in) in length.
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. The only reliable recent records are from Réunion.
