Acteon panamensis is a species of sea snail, a marine gastropod mollusc in the family Acteonidae.

(Original description) The apex of the shell is badly eroded, but apparently blunt.

The sculpture consists of (on the penultimate whorl four) sharp distant spiral, fine, microscopically punctate, incised lines.

The outer lip is sharp, simple, or minutely notched by the incised spiral lines.

The columella is straight, short and has a single obscure fold near the middle, which lags behind the aperture.
