Anthony Tillmon Williams (December 12, 1945 – February 23, 1997) was an American jazz drummer.

Williams first gained fame as a member of Miles Davis‘ “Second Great Quintet“, and later pioneered jazz fusion with Davis’ group and his own combo, the Tony Williams Lifetime. In 1970, music critic Robert Christgau described him as “probably the best drummer in the world”. Williams was inducted into the Modern Drummer Hall of Fame in 1986.

Williams was born in Chicago and grew up in Boston. He is of African, Portuguese, and Chinese descent. He studied with drummer Alan Dawson at an early age, and began playing professionally at the age of 13 with saxophonist Sam Rivers. Saxophonist Jackie McLean hired Williams when he was 16.

At 17 in 1963 Williams gained attention by joining Miles Davis in what was later dubbed Davis’s Second Great Quintet. Williams was a vital element of the group, called by Davis in his autobiography “the center that the group’s sound revolved around.” His playing helped redefine the role of the jazz rhythm section through the use of polyrhythms and metric modulation. Meanwhile, he recorded his first two albums as leader for Blue Note label, Life Time (1964) and Spring (1965). He also recorded as a sideman for the label including, in 1964, Out to Lunch! with Eric Dolphy and Point of Departure with Andrew Hill. Williams lived and taught in the San Francisco Bay Area until his death from a heart attack following routine gallbladder surgery. One of his final recordings was The Last Wave by the trio known as Arcana, a release organized by Bill Laswell.
