Tunku Ibrahim Ismail was born on at 22 November 1958, Sultanah Aminah Hospital, Johor Bahru, Johor, Malaya during the reign of his great grandfather, Sultan Ibrahim. He was the eldest son of Sultan Iskandar by his first wife Josephine Ruby Trevorrow (2 December 1935 – 1 June 2018), an English lady from Torquay, whom Sultan Iskandar (then Tunku Mahmud) met while he was studying in England. Trevorrow, a proprietor by profession, took on the name of "Kalsom binti Abdullah" for a time following her marriage to Tunku Iskandar. His mother has since remarried and lived in England.

His great-grandfather, Sultan Ibrahim died in London on 8 May 1959, thus, Tunku Ibrahim Ismail's grandfather, Ismail of Johor succeeded him as Sultan of Johor. Ibrahim Ismail moved up to second in line to the throne, after his father.

The late Sultan Iskandar sent him to complete his secondary education at Trinity Grammar School in Sydney, Australia from 1968 until 1970. After finishing his high school, he was sent to Pusat Latihan Tentera Darat (PULADA) in Kota Tinggi for basic military training. He also received military training in the US–at Fort Benning, Georgia and later at Fort Bragg, North Carolina.

Tunku Ibrahim Ismail was appointed as the Tunku Mahkota of Johor on 4 July 1981, and had been primarily residing at Istana Pasir Pelangi since then. Tunku Ibrahim was the regent of Johor between 26 April 1984 and 25 April 1989 when his father served his term as the Yang di-Pertuan Agong of Malaysia. In recent years, Tunku Ibrahim gradually took over some of the state duties and functions from his aging father; these included the 211th Conference of Rulers, whereby Tunku Ibrahim and Tengku Abdullah, the Tengku Mahkota of Pahang represented their fathers in the meetings, among some other state functions.

A motorcycle enthusiast, Sultan Ibrahim is well-known as the founder of the annual motorcycling tour event, Kembara Mahkota Johor.
