The Yamtuan Besar (Jawi: يمتوان بسر), officially Yang di-Pertuan Besar of Negeri Sembilan (lit. "He Who Is Made a Great Lord", Jawi: يڠ دڤرتوان بسر), is the royal title of the ruler of the Malaysian state of Negeri Sembilan. The Yang di-Pertuan Besar of Negeri Sembilan is elected by a council of ruling chiefs in the state, known as the Undangs. This royal practice has been followed since 1773. The Yamtuan Besar is elected from among the four leading princes of Negeri Sembilan (Putera Yang Empat); the Undangs themselves cannot stand for election and their choice of a ruler is limited to a male Muslim who is Malay and also a "lawfully begotten descendant of Raja Radin ibni Raja Lenggang", the 4th Yamtuan.

This unique form of government later inspired the first Prime Minister of Malaysia, Tunku Abdul Rahman, to implement a form of rotational constitutional monarchy for a newly independent Federation of Malaya (now Malaysia). Thus, the office of Yang di-Pertuan Agong was created.
