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 and the Percussive Arts Society Hall of Fame in 1997.

Williams was born in Chicago, Illinois, and grew up in Boston, Massachusetts. He was of African, Portuguese, and Chinese descent. He studied with drummer Alan Dawson at the age of 11, and began playing professionally at the age of 13 with saxophonist Sam Rivers. Saxophonist Jackie McLean hired Williams when he was 16.

At 17, 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 a leader for the Blue Note label, Life Time (1964) and Spring (1965). He also recorded as a sideman for the label including the classics Out to Lunch! with Eric Dolphy and Point of Departure with Andrew Hill, both in 1964.

In 1969 Williams formed the Tony Williams Lifetime, with John McLaughlin on guitar and Larry Young on organ. Lifetime was a pioneering band of the fusion movement.
