Megapomponia is a genus of cicadas from Southeast Asia containing the world's largest cicadas species. It was erected by Boulard to accommodate the world's largest cicada species, Megapomponia imperatoria, the type species of Megapomponia. Boulard included seven species in Megapomponia. Lee and Sanborn, however, re-transferred two species to Pomponia, Pomponia decem and Pomponia rajah.
