Michael Babatunde Olatunji (born April 7, 1927 – April 6, 2003) was a Nigerian drummer, educator, social activist, and recording artist.

Olatunji was born in the village of Ajido, near Badagry, Lagos State, in southwestern Nigeria. A member of the Yoruba people, Olatunji was introduced to traditional African music at an early age. He read in Reader's Digest magazine about the Rotary International Foundation's scholarship program and applied for it. He went to the United States of America in 1950.

Olatunji received a Rotary scholarship in 1950 and was educated at Morehouse College in Atlanta, Georgia, where he desired to, but never sang in the Morehouse College Glee Club. Olatunji was a good friend of Glee Club director Dr. Wendell P. Whalum and collaborated with him on a staple of the choir's repertoire, "Betelehemu", a Nigerian Christmas carol. After graduating from Morehouse, he went on to New York University to study public administration. There, he started a small percussion group to earn money on the side while he continued his studies.

After hearing Olatunji perform with the 66 piece Radio City Music Hall orchestra Columbia Records A&R man John Hammond signed Olatunji to the Columbia label in 1957. Two years later he released his first of six records on the Columbia label, called Drums of Passion. Drums of Passion became a major hit and remains in print; it introduced many Americans to world music. Drums of Passion also served as the band's name.

Olatunji won a following among jazz musicians, notably creating a strong relationship with John Coltrane, with whose help he founded the Olatunji Center for African Culture in Harlem. This was the site of Coltrane's final recorded performance. Coltrane wrote the composition "Tunji" on the 1962 album Coltrane in dedication to him. Olatunji recorded with many other prominent musicians (often credited as "Michael Olatunji"), including Cannonball Adderley (on his 1961 African Waltz album), Horace Silver, Quincy Jones, Pee Wee Ellis, Stevie Wonder, Randy Weston, and with Max Roach and Abbey Lincoln on the pivotal Freedom Now Suite aka We Insist!, and with Grateful Dead member Mickey Hart on his Grammy-winning Planet Drum projects. He is also mentioned in the lyrics of Bob Dylan's "I Shall Be Free" as recorded on the album The Freewheelin' Bob Dylan.

In 1969, Carlos Santana had a major hit with his cover version of "Jin-go-lo-ba" from Olatunji's first album, which Santana recorded on his debut album, Santana, as "Jingo". Olatunji's subsequent recordings include Drums of Passion: The Invocation (1988), Drums of Passion: The Beat (1989) (which included Airto Moreira and Carlos Santana), Love Drum Talk (1997), Circle of Drums (2005; originally titled Cosmic Rhythm Vibrations, with Muruga Booker and Sikiru Adepoju), and Olatunji Live at Starwood (2003 – recorded at the 1997 Starwood Festival with guest Halim El-Dabh. He also contributed to Peace Is the World Smiling: A Peace Anthology for Families on the Music for Little People label (1993).

His big break came with the release of his debut album, Drums of Passion in 1960.
