NBC shared the big news Monday on the show's Twitter account.
"[Pharrell] has already made a considerable impact as a mentor, drawing on an impressive track record as both a producer and performer," Paul Telegdy, NBC's president of alternative programming, said in a statement. "It is a perfect fit for The Voice as we evolve and reach for new heights with this franchise. It feels like we are welcoming an existing family member home."
Added executive producer Mark Burnett: "I am thrilled to have Pharrell come back to The Voice family, and this time ... as a coach. Continuing in The Voice tradition of having the biggest and most current music stars as coaches, Pharrell fits perfectly."
In February, CeeLo Green announced that he was departing the show permanently. Per NBC, the rest of the coach line-up will be confirmed at a later date.
The Voice, currently in its sixth season, airs Mondays and Tuesdays at 8/7c on NBC.
