Poptella is a genus of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins. The fishes in this genus are found in tropical South America. The name of this genus honours the Dutch ichthyologist Canna Maria Louise Popta who was a Curator of Reptiles, Amphibians and Fishes at the Rijksmuseum van Natuurlijke Historie in Leiden and who described the type species of this genus as Tetragonopterus longipinnis in 1901, donating one of the types to Carl H. Eigenmann’s collection at Indiana University.
