Ronnie Rancifer is an African American musician and songwriter, noted for being the keyboardist for The Jackson 5 from their early Gary, Indiana days until the end of their famed career at Motown. The label presented Rancifer and drummer Johnny Jackson as the cousins of Jackie, Tito, Jermaine, Marlon, Michael, but neither Rancifer nor Johnny Jackson are related to the Jacksons.

Besides playing keys for the Jackson 5, Rancifer also worked as a songwriter on some of their albums.
