Tuanku Munawir ibni Almarhum Tuanku Abdul Rahman (Jawi: توانكو مناور ابن المرحوم توانكو عبدالرحمن; 22 March 1922 – 14 April 1967) was the ninth Yang Di-Pertuan Besar (Grand Ruler) of the Malaysian State of Negeri Sembilan.

He was the eldest son of the first Yang Di-Pertuan Agong (King of Malaysia), Tuanku Abdul Rahman with his second consort Tunku Maharun.

His younger brother, Tuanku Ja'afar succeeded him after his death due to the relatively young age of his son.

Upon his return to Malaya, Munawir served the public sector at the Seremban Land Office, Negeri Sembilan.

On 5 April 1960, Tunku Munawir was installed as the ninth Yang di-Pertuan Besar of Negeri Sembilan.
