Oenopota aleutica is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

Its color varies from pure white to dark red brown.

The outer lip is sharp, thin, strongly flexuous, produced below.

The sculpture consists of longitudinal ribs thirteen or fourteen on the body whorl, obsolete on the lower third of the whorl and not extending to the suture, below which is a smooth band only marked by oblique lines of growth.

[1] This species occurs off Alaska, from Cape Sabine to the Fuca Strait.
