Tanner Laczynski (born June 1, 1997) is an American professional ice hockey center currently playing for the Lehigh Valley Phantoms under contract to the Philadelphia Flyers of the National Hockey League (NHL).
Laczynski made his NHL debut against the New York Islanders on April 3, 2021. After skating with the team for five games, Laczynski suffered a torn acetabular labrum in his right hip. He received surgery for the injury on April 26, with an expected recovery time of 16 weeks. After only two days of attending the Flyers' 2021 training camp, head coach Alain Vigneault announced that Laczynski required another surgery on the opposite hip, and that he would likely miss the entirety of the 2021–22 NHL season. He ultimately appeared in 28 games for the Phantoms during the 2021–22 season, recording seven goals and 17 points in the process. He also appeared in one game with the Flyers. On July 26, 2022, the Flyers signed Laczynski to a two-year, $1.525 million contract extension.
