John Henry "Jabo" Starks (/ˈdʒæboʊ/; October 26, 1937 – May 1, 2018), sometimes spelled Jab'o, was an American funk and blues drummer best known for playing with James Brown as well as other notable musicians including Bobby Bland and B.B. King. A self-taught musician, he was known for his effective and clean drum patterns. He was one of the originators of funk drumming, and is one of the most sampled drummers.

Starks was born in Jackson, Alabama, to Prince Starks and Ruth Watkins. One of five children, he was nicknamed "Jabo" as a newborn. He grew up in Mobile, Alabama. In the seventh grade, he was captivated by drumbeats at a Mardi Gras parade in Mobile and decided to pursue drumming. He was self-taught and had no formal training. He said he "learned a lot from listening" to music. Early on, he listened to blues music and was influenced by the gospel music he heard in church. One of his drum idols was Shep Sheppard of the Bill Doggett band. He graduated from Mobile County Training School in 1955, at the time a high school. He then performed at the Harlem Duke Social Club where he backed notable blues and R&B musicians including John Lee Hooker, Smiley Lewis, Clarence "Gatemouth" Brown, Big Mama Thornton and Howlin' Wolf.

In 1959, Starks joined Bobby Bland's band and was the youngest member of the band. He said band members Pluma Davis and Joe Scott taught him the importance of holding the drum rhythm steady and having other musicians lock-in with drums. He said musically that was the best band he played with. He was with the band from 1959 to 1965 and recorded on the band's releases over this period, including "Turn on Your Love Light", "Stormy Monday Blues", "That's the Way Love Is", "I Pity the Fool" and "Don't Cry No More". He also recorded with other artists during this time such as Junior Parker and Joe Hinton, on songs "Driving Wheel" and "Funny".

In 1965, Starks joined James Brown's band. From 1965 to 1970, the band had two drummers, Starks and Clyde Stubblefield. Starks came primarily from a blues background whereas Stubblefield from a soul and jazz background. They each performed solo on songs that fit their style. The two "created the grooves on many of Brown's biggest hits, and laid the foundation for modern funk drumming in the process." In 1970, the band went through a major transformation with Stubblefield leaving the group in late 1970. Starks continued performing with the reconfigured band which became known as The J.B.'s. Band members included bassist Bootsy Collins and rhythm guitarist Catfish Collins who along with Starks formed the rhythm section. The band also included trombonist Fred Wesley. Starks toured and recorded with Brown until 1976. Starks' recordings during his eleven-year association with Brown include "The Payback", "Sex Machine", "Soul Power", "Super Bad", "Talkin' Loud and Sayin' Nothing", "Doing It to Death", "Papa Don't Take No Mess", "Licking Stick – Licking Stick". He also backed artists produced or managed by Brown, most notably Lyn Collins and Bobby Byrd, as well as the independent works released by The J.B.'s.

Often uncredited, Starks and Stubblefield rank as two of the most sampled drummers on contemporary hip hop and R&B recordings. Starks’ drum patterns have been sampled by LL Cool J, Kendrick Lamar, The Roots, A Tribe Called Quest, Black Eyed Peas, Kool Moe Dee, Rob Base and DJ E-Z Rock, Total and others. About the lack of recognition for his work, he said: "the least they could do is say where they got [the samples] from."

Starks left Brown's band in mid-1970s and joined blues artist B.B. King. Starks was well versed in blues music in his early career. In regard to his transition from uptempo funk to laid-back blues, he said "to me, everything stems from playing the blues anyway." He toured and recorded with King for six years. His recordings with King include the albums Lucille Talks Back and King Size.

Starks and Stubblefield remained friends. In 1999, they performed on The J.B.'s album Bring the Funk on Down. The duo went on to release original music as the Funkmasters. They released the album Find the Groove in 2001 and the album Come Get Summa This in 2006. They released an instructional video titled Soul of the Funky Drummers. In 2007, the duo joined Bootsy Collins for the first tribute concert in memory of James Brown and performed on the soundtrack for the movie Superbad.

In his later years Starks lived in Mobile, Alabama. From the mid-1990s onward, when not touring or recording, he performed five nights a week at the Picolo Restaurant and Red Bar in Grayton Beach, Florida, and on Sundays he played drums at his church in Mobile. He performed until March 2018. He said over the years he learned little tricks to help him maintain his drumming skills.
