Stenotatus is an extinct genus of cingulate, belonging to the family Dasypodidae.

Stenotatus was a small to medium-sized armadillo, not exceeding 4 kilograms in weight.

The osteoderms composing its mobile armor had three pronounced longitudinal ridges, and it only had a single caudal row of quite narrow piliferous holes.

Other species later attributed to this genus are S. hesternus, S. ornatus, S. centralis and S. planus, all coming from Miocene terrains of Argentina.

It is however still unclear if those two genera constitute a monophyletic group comprising Stenotatus.
