The Menteri Besar of Negeri Sembilan is the head of government in the Malaysian state of Negeri Sembilan. According to convention, the Menteri Besar is the leader of the majority party or largest coalition party of the Negeri Sembilan State Legislative Assembly.

The 10th and current Menteri Besar of Negeri Sembilan is Mohamad Hasan, who took office on 25 March 2004.

According to the state constitution, the Yang di-Pertuan Besar of Negeri Sembilan shall first appoint the Menteri Besar to preside over the Executive Council and requires such Menteri Besar to be a member of the Legislative Assembly who in his judgment is likely to command the confidence of the majority of the members of the Assembly, must be an ethnic Malay who professes the religion of Islam and must not a Malaysian citizen by naturalisation or by registration. The Yang di-Pertuan Besar on the Menteri Besar's advice shall appoint not more than ten nor less than four members from among the members of the Legislative Assembly.

The member of the Executive Council must take and subscribe in the presence of the Yang di-Pertuan Besar the oath of office and allegiance as well as the oath of secrecy before they can exercise the functions of office. The Executive Council shall be collectively responsible to the Legislative Assembly. The members of the Executive Council shall not hold any office of profit and engage in any trade, business or profession that will cause conflict of interest.

If a government cannot get its appropriation (budget) legislation passed by the Legislative Assembly, or the Legislative Assembly passes a vote of "no confidence" in the government, the Menteri Besar is bound by convention to resign immediately. The Yang di-Pertuan Besar's choice of replacement Menteri Besar will be dictated by the circumstances. A member of the Executive Council other than the Menteri Besar shall hold office during the pleasure of the Yang di-Pertuan Besar, unless the appointment of any member of the Executive Council shall have been revoked by the Yang di-Pertuan Besar on the advice of the Menteri Besar but may at any time resign his office.

Following a resignation in other circumstances, defeated in an election or the death of the Menteri Besar, the Yang di-Pertuan Besar will generally appoint as Menteri Besar the person voted by the governing party as their new leader.
