Brachypnoea is a genus of leaf beetles in the subfamily Eumolpinae. It is mostly found in the Neotropical realm, though there are also eight known species in the Nearctic realm.

The genus was originally named Noda, named by Chevrolat in Dejean's Catalogue in 1836. However, this was preoccupied by Noda Schellenberg, 1803, a genus in Diptera. Two replacement names were made for Noda: Brachypnoea, by Gistel in 1848, and Nodonota by Édouard Lefèvre in 1885. Since Brachypnoea was published first, it has priority over Nodonota.
