Grand Daddy I.U. is an American rapper and record producer from Queens, New York. He was primarily active during the golden age of hip hop and was a member of the Juice Crew. He states that his stage name is similar to the pronunciation of his first name "Ayub" (ah-yoob).

Grand Daddy I.U. was raised in Hempstead, Long Island, and was encouraged to begin performing by his brother. He recorded a demo tape and gave it to Biz Markie, who signed him to the label Cold Chillin' Records in 1989. In 1990, he released his debut album Smooth Assassin, which spawned his one and only hit "Something New". He became noted for his high-end sartorial choices, always appearing in public wearing a suit and tie.

Grand Daddy I.U. did ghostwrite for Biz Markie and Roxanne Shanté but became disenchanted with Markie over a dispute involving publishing credits for the tracks on his debut. He released his second album Lead Pipe in 1994, but the album received little promotion, causing I.U. to quit rapping for nearly a decade.

Grand Daddy I.U. continued to do production work in hip-hop for groups and artists such as Das EFX, Heltah Skeltah, KRS-One and Ice-T. His first album in thirteen years, Stick to the Script, was released in 2007. His latest album, P.I.M.P. (Paper Is My Priority, was released in 2015.
