Mason Lohrei (/ˈloʊraɪ/; born January 17, 2001) is an American professional ice hockey defenseman currently playing for the Boston Bruins of the National Hockey League (NHL). He previously played college ice hockey for Ohio State University in the National Collegiate Athletic Association (NCAA). He is the first player in NHL history to have been born in the state of Louisiana.
Lohrei was born in Baton Rouge while his father, David, was head coach of the East Coast Hockey League's Baton Rouge Kingfish. He moved with his family as a child first to Pennsylvania and then Wisconsin where he grew up. He attended Middleton High School in Middleton, Wisconsin but transferred after his freshman year to Culver Academies in Culver, Indiana. As a sophomore at Culver, he made the decision to switch from forward to defense in order to get more playing time.
On April 24, 2025, after the Bruins season ended, Lohrei was named to the United States team for the 2025 IIHF World Championship. It was his first time representing the U.S. in any international competition. Lohrei appeared in five games, scoring one goal and two assists, and helped Team USA win their first gold medal since 1933.
