🏀 Correct! The Boston Celtics are tied for the most NBA championships in league history, with 17 titles. Their dominance began in the 1950s and peaked in the 1960s under legendary coach Red Auerbach and center Bill Russell, who led the team to 11 championships in just 13 seasons. That dynasty cemented the Celtics as the NBA’s most storied franchise. In later decades, they remained a consistent force, adding titles in 1974, 1976, and again in 2008 with the Big Three era of Paul Pierce, Kevin Garnett, and Ray Allen. With a passionate fanbase, historic rivalries—especially with the Lakers—and a tradition of hard-nosed, team-oriented basketball, the Celtics have influenced the sport culturally and competitively. Their championship legacy is the stuff of legend, and it earns them their rightful place as the correct answer to this question.
