Brachyrhaphis is a genus of poeciliids native to freshwater habitats in Central America. Most are restricted to Panama and Costa Rica, but B. holdridgei also occurs in Nicaragua and B. hartwegi is from Mexico and Guatemala. A phylogenetic analysis published in 2015 suggested that Brachyrhaphis may not be of a monophyletic group.
