Citharomangelia boakei is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

The shell closely resembles Citharomangelia africana (G. B. Sowerby III, 1903), but it is smaller and with more evenly convex whorls.

The color is pinkish white, shining, with a subsutural interrupted chestnut band, and another about the top of the aperture.

The lower half of the body whorl is pale chestnut.

The outer lip is thickened, internally minutely crenulated.
