The Mon language (; ) is an Austroasiatic language spoken by the Mon people, who live in Myanmar and Thailand. Mon, like the related Khmer language but unlike most languages in mainland Southeast Asia, is not tonal. Mon is spoken by more than a million people today. In recent years, usage of Mon has declined rapidly, especially among the younger generation. Many ethnic Mon are monolingual in Burmese. In Myanmar, the majority of speakers live in Mon State, followed by Tanintharyi Region and Kayin State.
