Woiwurrung and Taungurung are Aboriginal languages of the Kulin nation of Central Victoria. Woiwurrung was spoken by the Woiwurrung and related peoples in the Yarra River basin, and Taungurung by the Taungurung people north of the Great Dividing Range in the Goulburn River Valley around Mansfield, Benalla and Heathcote. They are often portrayed as distinct languages, but they were mutually intelligible. Ngurai-illamwurrung (Ngurraiillam) may have been a clan name, a dialect, or a closely related language.

The Woiwurrung, also spelt Woi-wurrung, Woi Wurrung, Woiwurrong, Woiworung, Wuywurung, are an Aboriginal Australian people of the Woiwurrung language group, in the Kulin alliance.
