Promartes is a genus of mustelids, now extinct, which existed during the Miocene period. The genus was first described in 1942, by E. S. Riggs, who identified the sister genus Zodiolestes at the same time, and assigned to the family Mustelidae. In 1998 it was assigned to the subfamily Oligobuninae. Five species have been identified in the genus: P. darbyi, P. gemmarosae, P. lepidus, P. olcotti, andP. vantasselensis, three of which were originally identified as members of Oligobunis.
