Prince Shah Karim al-Hussaini (13 December 1936 – 4 February 2025), known simply as Aga Khan IV, was the 49th Imam of Nizari Isma'ili Shia Islam from 1957 until his death in 2025. He inherited the Nizari imamate and the title of Aga Khan at the age of 20 upon the death of his grandfather, the Aga Khan III. During his Imamate, he was also known by the religious title Mawlānā Hazar Imam by his Isma'ili followers.

Al-Husseini's net worth was estimated at over US$13.3 billion by Vanity Fair in 2013. Forbes included al-Husseini in its list of the world's fifteen richest royals, though he held no political sovereignty or territorial authority. The designation referred to his hereditary role as Imam of the Nizari Ismailis, not to any formal royal or monarchical status. He was the founder and chairman of the Aga Khan Development Network, one of the largest private development networks in the world.
