The Sweden men's national ice hockey team (Swedish: Sveriges herrlandslag i ishockey) is governed by the Swedish Ice Hockey Association. It is one of the most successful national ice hockey teams in the world and a member of the so-called "Big Six", the unofficial group of the six strongest men's ice hockey nations, along with Canada, the Czech Republic, Finland, Russia and the United States.

The team's nickname Tre Kronor, meaning "Three Crowns", refers to the emblem on the team jersey, which is found in the lesser national coat of arms of the Kingdom of Sweden. The first time this emblem was used on the national team's jersey was on 12 February 1938, during the World Championships in Prague.

The team has won numerous medals at both the World Championships and the Winter Olympics. In 2006, they became the first team to win both tournaments in the same calendar year, by winning the 2006 Winter Olympics in a thrilling final against Finland by 3–2, and the 2006 World Championships by beating Czech Republic in the final, 4–0. In 2013 the team was the first team to win the World Championships at home since the Soviet Union in 1986. In 2018, the Swedish team won its 11th title at the World Championships. In 2021 Sweden failed to reach the playoffs for the first time after the tournament implemented the playoff system, placing 9th, tying their 1937 team for their worst placement in tournament history.
