The Regimental Sergeant Major of the Malaysian Armed Forces (; Jawi: ) is the highest appointment attainable within the other ranks of the Malaysian Armed Forces. The office holder serves as the principal adviser to the Chief of Defence Force on matters relating to other ranks and acts as their representative within the Armed Forces Headquarters. The appointment also carries responsibility for overseeing and coordinating the regimental sergeant majors or warrant officers of each service branch.
The office is located at Wisma Kementah, commonly known as Wisma Pertahanan, the administrative centre of the Malaysian Armed Forces.
The appointment is open to all branches of the Armed Forces, and the appointee is selected from among the senior warrant officers of each service, namely the Regimental Sergeant Major of the Army (), the Warrant Officer of the Navy (), and the Warrant Officer of the Air Force ().
The current Regimental Sergeant Major of the Malaysian Armed Forces is Warrant Officer Class 1 Shahamrie Abdullah of the Malaysian Army, who assumed the appointment on 2 April 2024, succeeding Warrant Officer Class 1 Hayazi Abdul Aziz.
The appointment of the Regimental Sergeant Major of the Malaysian Armed Forces was created on 6 October 2019, with Warrant Officer Class 1 Hayazi Abdul Aziz of the Malaysian Army serving as the inaugural holder.
Prior to 2019, no equivalent position existed within the Malaysian Armed Forces Headquarters (MAFHQ). At that time, senior warrant officers of each service branch reported directly to the Chief of Staff of the Malaysian Armed Forces Headquarters (CS MAFHQ; ) on matters concerning other ranks. This arrangement prompted the Armed Forces leadership to establish a dedicated post to act as the principal representative of other ranks within MAFHQ, ensuring their voice and welfare were adequately addressed and safeguarded.
In 2019, two new appointments were introduced for other ranks at MAFHQ: the Regimental Sergeant Major of the Malaysian Armed Forces and the Ceremonial Regimental Sergeant Major of the Malaysian Armed Forces (). The latter serves as the senior authority for ceremonial matters, military parades, and functions as master of ceremony at official events involving the Malaysian Armed Forces.
The Malaysian Armed Forces Headquarters (MAFHQ) has defined six primary roles for the Regimental Sergeant Major of the Malaysian Armed Forces:
In addition to these primary responsibilities, the Regimental Sergeant Major of the Malaysian Armed Forces also acts as chairman of the formal welcoming party for visiting senior enlisted personnel and other ranks from foreign armed forces.
Since its establishment, two individuals have been appointed to the post of Regimental Sergeant Major of the Malaysian Armed Forces. The list is as follows:
