The deal was announced on Wednesday.
With stars Jonathan Toews and Patrick Kane leading the way, the 40-year-old Bowman has overseen two championship runs since he replaced Dale Tallon as general manager in July 2009.
They won it all in 2010, ending a 49-year drought, but had to overhaul their supporting cast due to salary cap restraints. Back-to-back first-round playoff exits followed, but the Blackhawks had a record start last season and beat Boston in the Stanley Cup finals.
That made Bowman the first general manager to win multiple championships since the NHL instituted a salary cap in 2005. He is entering his 13th season with the Blackhawks.
