Propebela nobilis is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.
The shell resembles that of Propebela rugulata. The spire, as a rule, is shorter than the aperture. The axial ribs are strongly projectant, and between them, round the angulated ultimate part of the whorl, a deepish concavity occurs, in which the transversal sculpture distinctly appears.
