It was reported back in April that the channel was in negotiations with Big Talk Productions to recommission the series.
Rev stars Tom Hollander as Adam Smallbone, a vicar who relocates from a rural parish in Suffolk to an inner-city London church.
Development on series three will commence this autumn, with a 2014 air date planned, Variety reports.
"We're absolutely delighted to have Rev back on the channel," said BBC Two Controller Janice Hadlow. "It's one of the real comedy jewels in BBC Two's crown."
Big Talk's Kenton Allen added: "Such is the brilliance of the Rev cast that getting everyone back together for further adventures is always challenging.
"But I'm delighted that we've managed to get Adam and his congregation back into church for what I hope will be an extraordinary third season of a show that is extremely special for all those involved."
Rev concluded its second series in December last year.
