Warrington's head of coaching and rugby Tony Smith said: "I am really excited by the prospect of getting to work with Brian. He's a championship player and his experience and know-how will be a real asset to the squad.
Carney, who is pleased to be joining Wolves and thankful of his time in Munster, commented: "I'm really looking forward to a new challenge with Warrington Wolves and am equally looking forward to working with the squad and Tony Smith and hope that I can add something to their game.
"I'd also like to thank the players and everyone involved in Munster for their time and efforts. I enjoyed my time there."
Carney scored five tries in 21 appearances for Munster between 2007 and 2008.
He gained four Ireland caps, scoring a try on his debut against Argentina on the 2007 summer tour and was selected in Ireland's 2007 Rugby World Cup squad.
Most recently, the 32-year-old winger got amongst the tries during Ireland's run through to the Bowl final at the IRB Rugby World Cup Sevens in Dubai in March.
