Stenotrema exodon, also known as the Alabama slitmouth, is a rare species of pulmonate land snail in the family Polygyridae.

The Alabama slitmouth's shell is horn-brown and covered in the thin, fine hairs typical of species in the Stenotrema genus.

The aperture lips are paler than the rest of the shell, protrude outwards, and possess a defined notch and short parietal tooth.

It is listed as imperiled globally and at the Tennessee state level.

[3] The species was first described by carcinologist Henry A. Pilsbry in the city of Woodville in Jackson County, Alabama.
