Palaemonetes is a genus of caridean shrimp comprising a geographically diverse group of fresh water, brackish and marine crustaceans. Conventionally, Palaemonetes includes the following species:[2]

Molecular data suggest however that Palaemonetes is not phylogenetically distinct from the genus Palaemon. Phylogenetically species of Palaemonetes, as well as those in the genera Exopalaemon and Couteriella, are nested within Palaemon. Phylogenetic affinities in these groups correspond better with geographical origin than conventional genus assignments.[3]
