Panthers general manager Dale Tallon made the announcement Tuesday, saying the dismissal was effective immediately. Horachek replaced Kevin Dineen as Panthers' coach on Nov. 8, and Florida went 26-36-4 under him.
Horachek had been the coach of Florida's AHL affiliate in San Antonio before being summoned to lead the Panthers.
Florida finished with the second-lowest point total in the NHL this season and missed the playoffs for the 12th time in 13 seasons. The Panthers last won a playoff series in 1996, the year they lost to Colorado in the Stanley Cup finals.
That group is not satisfied until we win a Stanley Cup. When we do win that Stanley Cup, I don't think we'll be satisfied then either. We're going to want another one. We have the group to do it. We have all the pieces. We just need to put them together.
