Which NHL team celebrated their 40th anniversary during the 2010–11 season? The Buffalo Sabres celebrated their 40th anniversary during that season.

The Sabres entered the NHL in 1970 as an expansion franchise, so the 2010–11 campaign marked 40 years since the team’s founding. Strictly speaking, it was the franchise’s 41st season because the 2004–05 NHL season was cancelled by a lockout; the team described the milestone as 40 seasons of play.

Buffalo marked the occasion with a strong visual callback to its early identity. The club brought back a version of its original crossed-swords logo and wore uniforms based on the blue-and-gold designs used from the inaugural 1970–71 season. The anniversary logo incorporated “1970” into the team emblem.

The Sabres finished 2010–11 with a 43–29–10 record and reached the playoffs, where they lost a seven-game first-round series to the Philadelphia Flyers. Their anniversary celebration therefore connected a modern playoff team with the franchise’s original look and history.
