Barry Trotz (born July 15, 1962) is a Canadian ice hockey executive, former player and coach.

On February 20, 2013, Lindy Ruff was fired by the Buffalo Sabres, making Trotz the longest-tenured head coach in the NHL.

He was also the second-longest tenured coach in the four major North American professional leagues, behind only Gregg Popovich of the National Basketball Association's San Antonio Spurs.

[1] During that time, Trotz played in 191 games, scoring 15 goals, adding 60 assists and accumulating 324 penalty minutes.

In 1987, he returned to the University of Manitoba as head coach, while also serving as a part-time scout for the Washington Capitals.

[7] When longtime Capitals general manager David Poile was hired by the newly established Nashville Predators, he decided to bring Trotz along to become the team's first head coach.

The Predators would fare no better in the playoffs, losing 4–1 to the San Jose Sharks in the opening round just as they did the year before.

Shortly after being eliminated by the Chicago Blackhawks in six games, on April 28, 2010, Trotz was named a finalist for the Jack Adams Award for NHL coach of the year alongside Joe Sacco of the Colorado Avalanche and Dave Tippett of the Phoenix Coyotes.

[citation needed] Despite the Predators inviting Trotz to work in their hockey operations department, he wanted to keep coaching.

They faced the defending champion Pittsburgh Penguins in the Semifinals and reached a 2–2 series tie with one win and one loss at home and on the road, before seizing the upper hand with a critical 6–3 victory at home for Game 5 and finally finishing them off 2–1 in overtime at Pittsburgh in Game 6 on a goal by Evgeny Kuznetsov to advance to the Conference Finals.

In the Stanley Cup Finals, they met the Vegas Golden Knights, an expansion team that won 51 games.

[25] Trotz was assistant coach for Canada at the IIHF World Championships three times: 2002, 2003 (when they won the gold medal) and 2009.

[27] The family previously resided in Brentwood, Tennessee; Clarendon, Virginia; and Garden City, New York.

[28] An active member of the Nashville community, Trotz won the Community Spirit Award in 2005 for various charitable works, including donating $500 to My Friends' House (a United Way agency) for each Nashville victory through several seasons; serving as an active board member for the Williamson County YMCA and the United Way; working closely with Best Buddies of Tennessee, a nonprofit organization dedicated to establishing a global volunteer movement that creates opportunities for one-to-one friendships, integrated employment and leadership development for people with intellectual and developmental disabilities.
