Euomphalus is a genus of fossil marine gastropods known to have lived from the Silurian to the Middle Permian.

[1][2] Euomphalus is characterized by a closely coiled shell with a depressed to slightly elevated spire and a channel-bearing angulation (a selenizone) on the upper surface of the whorls.

[1] Amphiscapha, Philoxene, and Straparollus are among similar related genera.

Serpulospira, also related, differs in having a broadly open spiral in the adult form.

Euomphalus is the type genus of the family Euomphalidae.
