Guerin, who turns 49 on Nov. 9, spent the past eight seasons with the Pittsburgh Penguins, including the past five as assistant GM.
"Everybody back in Pittsburgh over the past 10 years have supported me and my family," Guerin said. "I'm extremely grateful. It's been a great ride, I've learned a lot, we've won a lot and I really do appreciate it."
Guerin was a player development coach from 2011-14. He won the Stanley Cup twice as a member of the Penguins front office (2016, 2017) and once as a player (2009). He also won the Cup with the New Jersey Devils in 1995.
"Bill has been a winner throughout his hockey career, and I am extremely pleased to be able to add his experience to our organization and the State of Hockey," Leipold said.
Added Pittsburgh center Sidney Crosby, who was a teammate of Guerin's with the Penguins from 2008-10: "I am happy for Billy, and I am going to miss having him around. He is a great leader and was always there for me since the day he came to Pittsburgh. I know he'll be a great general manager."
Selected by the Devils with the No. 5 pick in the 1989 NHL Draft, Guerin had 856 points (429 goals, 427 assists) in 1,263 games with the Devils, Edmonton Oilers, Boston Bruins, Dallas Stars, St. Louis Blues, San Jose Sharks, New York Islanders and Penguins. He had 74 points (39 goals, 35 assists) in 140 Stanley Cup Playoff games.
"I'm really looking forward to getting going here," Guerin said. "We've got a lot of work to do, but there's a ton of potential."
