Nemolestes is an extinct genus of sparassodont that lived in South America during the Lutetian and Bartonian stages of the Eocene epoch.
Taxonomy Silvenator brasiliensis, a taxon known from the Itaboraí fossil site of Brazil, was originally assigned to the genus Nemolestes; however, it was later reclassified as belonging to its own separate monotypic genus on the basis of its dental dissimilarity to other species of Nemolestes.
Distribution Nemolestes lagunafriensis is, as the name suggests, known from Laguna Fría, a Lutetian fossil site in Chubut, Argentina. Nemolestes spalacotherinus, the type species, is known from the Bartonian site of Colhué Huapí Norte in Chubut.
