Brian "Boosh" Boucher (pronounced Boo-shay) (born January 2, 1977) is an American professional ice hockey goaltender for the Philadelphia Flyers of the National Hockey League (NHL).
Boucher was drafted by the Philadelphia Flyers in the first round of the 1995 NHL Entry Draft, 22nd overall. He began play with the Flyers in the 1999–2000 season, taking the starting position from veteran John Vanbiesbrouck and helped the team secure the Eastern Conference and Atlantic Division regular season titles while leading the NHL in goals against average at 1.91. In the playoffs, he backstopped his team to the Eastern Conference Finals. Along the way, he recorded several memorable moments, including a five-overtime victory against the Pittsburgh Penguins and a sprawling save against Patrik Elias of the New Jersey Devils. Although the Flyers were ahead 3-1 in the Eastern Conference Finals against the Devils and despite the return of the injured Eric Lindros, Boucher and the Flyers lost in seven games to the eventual Stanley Cup champion New Jersey Devils. In 2000–01, however, a weak start saw him lose his starting position to Roman Čechmánek.
He was traded with draft picks to the Phoenix Coyotes on June 12, 2002, for Michal Handzuš and Robert Esche. While with Phoenix, he broke the modern-day NHL record for the longest shutout streak by a goalie, going unscored upon for 332 minutes, or 5 and a half games. On February 1, 2006, Phoenix traded him to the Calgary Flames along with Mike Leclerc in exchange for Steven Reinprecht and Philippe Sauvé.
