The Cua language (also known as Bòng Mieu) is a Mon–Khmer language spoken in the Quang Ngai and Quang Nam provinces of Vietnam. Cua dialects include Kol (Kor, Cor, Co, Col, Dot, Yot) and Traw (Tràu, Dong). Maier & Burton (1981) is currently the most extensive Cua dictionary to date.
Paul Sidwell (2009) considers Cua to constitute an independent primary branch of Bahnaric, which he calls East Bahnaric. Cua has also had extensive contact with North Bahnaric languages. However, Sidwell (2002) had previously classified Cua as a Central Bahnaric language.
