Serengetilagus is an extinct genus of lagomorph in the family Leporidae.

It lived in the Pliocene of Kenya and Tanzania and the Late Miocene of Chad.

[1] Serengetilagus is the best-represented taxon from Laetoli, with approximately 34 percent of fossils in the Laetolil Beds attributed to this genus.

Additional specimens from Angola, Morocco[3] and Ukraine[4] may also belong to this genus.

It had a number of specific features unknown in other lagomorphs, such as a "missing" mesoflexid on its third premolar.
