Baeolidia scottjohnsoni is a species in the family Aeolidiidae found in the Marshall Islands and Hawaii, United States.
The holotype of this species was collected at a depth of 10 m at Enewetak Pinnacle, Kwajalein Atoll, Marshall Islands and a second specimen from Hawaii was included in the description.
The body is brown with a dense pattern of opaque white pigment over much of the dorsal surface. Rhinophores are stout with long papillae on the surfaces. Cerata are slightly flattened and coloured brown on the exterior faces but have conspicuous blue and white curved bands on the surfaces facing inwards over the back.
Found in Halimeda kanaloana and Caulerpa, but it feeds on the anemone Bunodeopsis medusoides.
