Trigonopterus is a genus of flightless weevils placed in the Cryptorhynchinae of Curculionidae. It is distributed in Australia, Indonesia and Melanesia. About 90 species had been formally described until March 2013, when a single paper more than doubled this number, agreeing with previous studies and a systematic barcoding study that many more species have yet to be described. As of October 2021, there were 480 described species.
The center of its diversity appears to be New Guinea where 51 or more species can be found in a single locality. Many of them are very similar to each other, but male genital characters and DNA barcoding allow a safe identification.
