Williams was born on April 5, 1973, in Virginia Beach, Virginia, the oldest of three sons of Pharaoh Williams, a handyman, and his wife Carolyn, a teacher. His roots extend for generations in Virginia and North Carolina, and one of his ancestors journeyed to West Africa in 1831, prompting other relatives to emigrate from America to Liberia in 1832. He met Chad Hugo in a seventh-grade summer band camp where Williams played the keyboards and drums and Hugo played tenor saxophone. They were also both members of a marching band; Williams played the snare drum while Hugo was drum major.

On March 31, 2014, Williams was announced as a new coach for the seventh season of The Voice, replacing CeeLo Green.

Comme des Garcons developed a unisex fragrance with Williams scheduled for release in late 2014. Kaws designed the bottle artwork.  In January 2015, Williams and Al Gore announced that they are teaming up to create a 7-continent "Live Earth" concert on June 18 to raise awareness about and pressure governments to act on climate change.

In 2015, a unanimous jury determined that Williams's 2013 hit song "Blurred Lines" was an infringement of the 1977 Marvin Gaye song "Got to Give It Up".
