The Lihir language () is an Austronesian language spoken in the Lihir island group, in New Ireland Province, Papua New Guinea. It is notable for having five levels of grammatical number: singular, dual, trial, paucal and plural. It is questionable whether the trial is indeed trial or whether it is paucal, leaving there being a paucal and a greater paucal.
