Aeolidiella glauca is a species of sea slug, an aeolid nudibranch in the family Aeolidiidae.
The body of this nudibranch attains a length of 45 mm. 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 cerata are covered with dense flecks of fawn-coloured pigment. The outer half of the oral tentacles and rhinophores are similarly pigmented.
The body is the host of the ectoparasitic copepods Doridicola agilis <small>Leydig, 1853</small> and Splanchnotrophus angulatus <small>Hecht, 1893</small>.
This species was described from Berry Head, Torbay, England. It has subsequently been reported from Norway, Great Britain, Ireland, Denmark, and the Atlantic coast of France south to Arcachon Bay.
