''Herpestes'' is a genus within the mongoose family Herpestidae. Several species in the family are known as slender mongooses. It is the type genus of the family, and comprises 5-6 living species, each with several

Characteristics

The living ''Herpestes'' species are sexually dimorphic, with females smaller than males. They range in weight from . They share several characteristics, including the shape of the

recognised 10 ''Herpestes'' species as valid in 2005. The extinct '' Herpestes lemanensis'' was excavated in tertiary depositions in the Loire Valley in central France and described in 1853. It most likely dates to the Late Oligocene. Phylogenetic analysis of African and Asian mongoose specimens revealed that they belong to three distinct genetic lineages; the two African lineages diverged in the Early Miocene around and , and the Asian ''Urva'' lineage at around . The following African mongooses are now placed in the genus ''Herpestes'':
