Wergaia or Werrigia is an Australian Aboriginal language in the Wimmera region of north-Western Victoria.

The Wergaia language consisted of four distinct dialects: Wudjubalug/Wotjobaluk, Djadjala/Djadjali, Buibadjali, Biwadjali.

[2] Wergaia was in turn apparently a dialect of the Wemba Wemba language, a member of the Kulinic branch of Pama–Nyungan.

[6][7] In mid-2021 a language revival project started up at the Wotjobaluk Knowledge Place, established in December 2020 at Dimboola.

A Wergaia language program would run over 20 weeks.
