Geophis sartorii, also known commonly as Sartorius' snail-sucker and the terrestrial snail sucker, is a species of snake in the family Colubridae.

The specific name, sartorii, is in honor of German-born Mexican naturalist Christian Carl Wilhelm Sartorius.

[3] G. sartorii is found in southeastern Mexico, and in Belize, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua.

[2] The preferred natural habitat of G. sartorii is forest, at altitudes from sea level to 2,000 m (6,600 ft).

[2] G. sartorii mimicks Micrurus elegans, a species of venomous coral snake with which it is sympatric.
