Stenotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.

Members of this genus are known as slitmouths.

These are typically small to medium-sized snails, with a velvety or hairy shell surface, and a narrow aperture which is usually closely guarded by well-developed "teeth".

The genus occurs throughout most of North America, from Alaska, though Canada and the United States, into Mexico.

[2] Genus Stenotrema contains the following species and subspecies:[2][3] See Euchemotrema for other closely related taxa, many of which are sometimes placed in Stenotrema.
