NBA championships are the ultimate goal for teams in the National Basketball Association. Each season, 30 teams compete in a regular season followed by playoffs, culminating in the NBA Finals. The team that wins the Finals is awarded the Larry O'Brien Championship Trophy. The NBA championship series is a best-of-seven format, meaning the first team to win four games is declared the champion. This prestigious title has been claimed by various teams, with the Boston Celtics and Los Angeles Lakers holding the most championships in league history.
