Undang

The Undang Yang Empat (Negeri Sembilan Malay: Undang Nan Ompek; Jawi: أوندڠ يڠ امڤت) are the ruling chiefs or territorial chiefs who play an important role in the election of a new Yang di-Pertuan Besar of Negeri Sembilan, Malaysia.

The Minangkabau who settled at Negeri Sembilan, in present-day Malaysia at the end of the 17th century ruled by a "penghulu" or headman who was chosen from the noble families of Sakai and Jakun belonging to the Biduanda clan.

By the early part of the 18th century, the leaders of these four territories started using the title "Undang" to distinguish themselves from other penghulu luak.

[1] The ruling chiefs are selected among the nobility in each luak (district), following matrilineal inheritance, part of the state's adat perpatih customs.

The Undangs themselves cannot stand for election and their choice of ruler is limited among the princes of Seri Menanti royal family who are:
