Tunku Abdul Rahman ibni Al-Marhum Sultan Ismail Al-Khalidi (25 November 1933–12 July 1988) was the younger son of Sultan Ismail of Johor as well as the younger brother of Sultan Iskandar of Johor.
Abdul Rahman held the post of Tunku Mahkota (or Crown Prince) for twenty years until shortly before his father's death in 1981.
His termination of his post generated considerable controversy for a brief period of time.
