Alexander Wennberg

Columbus Blue Jackets

Wennberg made his NHL debut on 9 October 2014, against the Buffalo Sabres, where he also recorded his first NHL point. He was reassigned to Columbus' American Hockey League (AHL) affiliate, the Springfield Falcons, after playing in seven NHL games, as defenceman Ryan Murray was activated off injured reserve. However, he was recalled to Columbus the next day after the team placed Matt Calvert on injured reserve. Wennberg scored his first career NHL goal on 22 December in a 5–1 loss to the Nashville Predators.

Wennberg missed the first five games of the 2015–16 season to recover from a concussion he suffered during the Blue Jackets' season opener against the New York Rangers. After returning, Wennberg was again injured in early November and was subsequently placed on injured reserve.

The following season, Wennberg played in 80 regular season games and recorded career-highs in goals (13) and assists (46). On 1 September 2017, he signed a new six-year, $29.4 million contract with the Blue Jackets carrying an annual salary cap hit of $4.9 million.

During the first game of the 2018 Stanley Cup playoffs, Wennberg was injured by a check from Washington Capitals forward Tom Wilson and was removed from the game. Due to this, the Blue Jackets earned a power play which Columbus scored on to tie the game. The Blue Jackets went on to win the game in overtime. Wennberg played two more games in the series but the Blue Jackets failed to advance.

Florida Panthers

On 8 October 2020, Wennberg was placed on waivers for the purpose of buying out the remaining three years on his contract. On the opening day of free agency, Wennberg was signed by the Florida Panthers to a one-year, $2.25 million contract on 9 October. He was signed by newly-installed general manager Bill Zito, who was formerly a part of the Blue Jackets organization. In a fresh start with the Panthers, in which the pandemic delayed and shortened the 2020–21 season, Wennberg responded with a career high 17 goals in 56 games, and added 12 assists while relied upon to provide responsible two-way play.^{[citation needed]}

Seattle Kraken

As a free agent from the Panthers, Wennberg was targeted and signed to a three-year, $13.5 million contract with the expansion club, the Seattle Kraken, on 28 July 2021. During training camp, Wennberg was placed on a line with fellow Swedes Calle Järnkrok and Marcus Johansson. Due to their shared lineage, the trio's line was quickly named the Swedish House Mafia. After missing the start of the preseason due to the birth of his first child, Wennberg made his Kraken preseason debut with the Swedish line on 1 October against the Edmonton Oilers. However, the line was broken up in the final preseason game after Järnkrok entered the NHL's COVID-19 protocols.

New York Rangers

On 6 March 2024, two days before the trade deadline, the Kraken traded Wennberg to the New York Rangers in exchange for a 2024 second-round and a conditional 2025 fourth-round draft pick. He made his debut with the Rangers on 9 March, recording one assist.

San Jose Sharks

In the 2024 off-season, Wennberg left the Rangers as a free agent and signed a two-year, $10 million contract with the San Jose Sharks.

On 8 October 2025, Wennberg was named an alternate captain for road games for the 2025–26 season. In January 2026, he signed a three-year, $18 million contract extension. On 27 March, he was named the Sharks' nominee for the King Clancy Memorial Trophy, awarded for leadership on and off the ice and humanitarian contributions to the community.

Wennberg finished the 2025–26 season with 55 points (18 goals, 37 assists) in 80 games, his most offensively productive season since 2016–17 with the Columbus Blue Jackets. He set career highs in goals, power play goals, and average ice time (20:27).

On 30 September 2026, Wennberg was once again named an alternate captain for the 2026–27 season, this time for home games.
