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 (7.480977°S 144.254009°E / -7.480977; 144.254009 (Babaguina)), Doibo (7.45766°S 144.271731°E / -7.45766; 144.271731 (Doibo/Babeio/Veiru)), Ero (7.446131°S 144.364831°E / -7.446131; 144.364831 (Ero)), Paile, Tipeowo, and Wowa (7.414287°S 144.315579°E / -7.414287; 144.315579 (Wowou)) villages in West Kikori Rural LLG and East Kikori Rural LLG of Gulf Province, near the Aird Hills and Kikori River tributaries.^[2][3]
