Herpetocetus is a genus of cetotheriid mysticete in the subfamily Herpetocetinae. Considerably smaller than modern baleen whales, Herpetocetus measured only 3 to 4 meters in length. Additionally, due to the structure of its jaw, it was unable to open its mouth as wide as modern baleen whales, making it incapable of lunge feeding.

== Taxonomy == There are four recognized species of Herpetocetus: H. scaldiensis, H. transatlanticus, H. bramblei, and H. morrowi. An additional unnamed species from Japan has been referred to the nomen dubium Mizuhoptera sendaicus in the past, but the undiagnostic nature of the holotype of the latter means that it cannot be confidently referred to M. sendaicus. thumb|Herpetocetus and other Half Moon Bay genera
