Yinwum is an extinct Paman language formerly spoken on the Cape York Peninsula of Queensland, Australia, by the Yinwum people. It is unknown when it became extinct,{{cite journal | author = Ernst Kausen | year = 2005 | title = Australische Sprachen | url = http://homepages.fh-giessen.de/kausen/klassifikationen/Australisch.doc}} but it was no longer spoken by the 1960s. Historically, it underwent some unusual phonological changes that are difficult to classify and understand in phonetic terms.
