Alexei Vyacheslavovich Emelin (Russian: Алексей Вячеславович Емелин; born 25 April 1986) is a Russians professional ice hockey defenceman who plays for the Dubai Red Stars of the Emirates Ice Hockey League. He was selected in the third round, 84th overall, by the Montreal Canadiens in the 2004 NHL Entry Draft. Emelin has also previously played for the Nashville Predators.
In a Kontinental Hockey League (KHL) game in 2009, Emelin sustained a face injury during a fight with Alexander Svitov; an orbital bone shattered and had to be rebuilt with metal plate. He has tried to avoid getting into fights ever since the incident.
On 30 June 2012, Emelin signed a two-year extension up until the end of the 2013–14 season.
During the lockout shortened 2012–13 season, Emelin established himself as a key member of the Canadiens' defensive core, often playing with fellow countryman Andrei Markov. He scored three goals and 12 points in 38 games for the Canadiens and finished with a plus-minus rating of +2. His season, however, was derailed by an injury during a game against the Boston Bruins on 6 April 2013, when Emelin collided with Bruins forward Milan Lucic, falling awkwardly and tearing a ligament in his left knee. As a result, Emelin missed the remainder of the regular season and the playoffs. On 31 October 2013, he signed a four-year contract extension with Montreal, lasting through the 2017–18 season.
On 19 December 2022, Emelin left Dinamo and transferred to HC Spartak Moscow for the remainder of the season.
