Alex Formenton (born September 13, 1999) is a Canadian professional ice hockey forward currently playing with the Ottawa Senators of the National Hockey League (NHL). He was selected in the second round, 47th overall, by the Senators in the 2017 NHL Entry Draft.
Formenton was drafted by the major junior London Knights in the 2015 OHL Priority Draft. In 2016, Formenton formally joined the Knights and recorded 16 goals and 34 points in 65 games. On the basis of that season, the Ottawa Senators selected him in the second round of the 2017 NHL Entry Draft, 47th overall.
Formenton was invited to the Ottawa Senators main training camp after attending its development camp in the summer of 2017. At the end of training camp, Ottawa retained him on its NHL roster to open the 2017–18 season and signed him to a three-year entry-level contract. Formenton made his NHL debut on October 7, 2017, becoming the youngest player to play a game for the contemporary Ottawa Senators. He was a healthy scratch after that game, and on October 17, he was returned by the Senators to continue his development with the London Knights. After the 2017–18 OHL season, Formenton was reassigned to the Belleville Senators, the Senators AHL affiliate.
