Porome, also known as Kibiri, is a Papuan language of southern Papua New Guinea.
Porome was classified as a language isolate by Stephen Wurm. Although Malcolm Ross linked it to the Kiwaian languages, there is no evidence for a connection apart from the pronouns 1sg amo and 2sg do (cf. proto-Kiwaian *mo and *oro).
There are over a thousand speakers in Babaguina (), Doibo (), Ero (), Paile, Tipeowo, and Wowa () villages in West Kikori Rural LLG and East Kikori Rural LLG of Gulf Province, near the Aird Hills and Kikori River tributaries.
Porome has 9 native consonants. /s/ occurs in loanwords. There are no glottal consonants.
There are five vowels, which are /a, e, i, o, u/.
Like the surrounding languages, Porome is a tonal language. It has 5 tones.
