Tricolia speciosa, common name the Mediterranean pheasant, is a species of sea snail, a marine gastropod mollusk in the family Phasianellidae.

The thin, shining shell has an ovate-elongate shape.

The interstices are covered with fine pink or yellowish obliquely descending lines.

The five, convex whorls are separated by deeply constricting sutures.

The posterior angle is occupied by a heavy callus.
