Ayer Kuning (Jawi: اءير كونيڠ) is a mukim and new village in Tampin District, Negeri Sembilan, Malaysia.[1] It borders Nyalas and Asahan, Malacca to the southwest and south, and Jementah, Johor on the southeast. The 1,276-metre tall Mount Ledang stands majestically near the tripoint between these states.
Traditionally, it is a chiefdom (luak) under the protection of Johol.
