Mecynorhina (frequently misspelled as Mecynorrhina; the original spelling used a single "r" and the misspelling is not in prevailing usage, therefore not valid under the ICZN) are beetles from the subfamily Cetoniinae, tribe Goliathini. The genus was created by Frederick William Hope, in 1837. According to the last work of De Palma & Frantz, the type species of the genus is Scarabaeus polyphemus Fabricius, 1781. The genus is spread throughout the tropical African region.
