Which NBA team did LeBron James first win a championship with?

LeBron James first won an NBA championship with the Miami Heat. He joined Miami as a free agent in 2010 alongside Dwyane Wade and Chris Bosh, forming one of the league's most celebrated “Big Three” teams.

The Heat reached the NBA Finals in James's first season but lost to the Dallas Mavericks in 2011. Miami returned the next year and defeated the Oklahoma City Thunder in the 2012 Finals. James averaged 28.6 points, 10.2 rebounds, and 7.4 assists during the series and won his first Finals MVP award.

That title was especially significant because James had previously reached the Finals with the Cleveland Cavaliers in 2007 without winning. He and Miami repeated as champions in 2013 by defeating the San Antonio Spurs. James later returned to Cleveland and won a championship there in 2016, then captured another title with the Los Angeles Lakers in 2020. Thus, Cleveland was his hometown team's first championship, but Miami was his first championship team.
