Aeolidiella glauca is a species of sea slug, an aeolid nudibranch in the family Aeolidiidae.

It is orange-brown in colour with extensive fawn or light brown surface pigment both on the dorsum and in a rim around the edge of the foot.

The outer half of the oral tentacles and rhinophores are similarly pigmented.

[3][4] The body is the host of the ectoparasitic copepods Doridicola agilis Leydig, 1853 and Splanchnotrophus angulatus Hecht, 1893.

[5] It has subsequently been reported from Norway, Great Britain, Ireland, Denmark, and the Atlantic coast of France south to Arcachon Bay.
