No franchise in North American professional basketball has gathered more hardware than the Boston Celtics. Their total of 18 NBA championships is the standard against which every other team measures itself, a tally assembled across nearly seven decades and four distinct eras of dominance. The banners that hang from the rafters tell a story that runs from the black-and-white footage of the Russell years through the Larry Bird rivalries of the 1980s and on to a modern side built around homegrown talent.

This page sets out the full record: the years, the opponents, the decisive figures and the context that makes Boston’s collection the most storied in the sport.

The complete list of Celtics titles

Boston’s championships span 1957 to 2024. The run of eight consecutive crowns in the middle of that stretch remains unmatched in the four major North American leagues and is widely regarded as the single most dominant sustained performance in basketball history.

The Russell era: a decade without equal

The foundation of everything was laid when Red Auerbach engineered the arrival of Bill Russell in 1956. A defensive center who changed how the game was understood, Russell turned Boston into a machine. The first title came in 1957, settled by a double-overtime Game 7 against the St. Louis Hawks. After a Finals loss to the same Hawks in 1958, the Celtics reeled off eight championships in succession, a sequence that no team has come close to matching.

Russell won 11 titles in 13 seasons, a figure unmatched by any player in league history. For the final two of those, in 1968 and 1969, he served as player-coach, becoming the first Black head coach to win a championship in a major American professional league. He was surrounded by Hall of Fame talent throughout: Bob Cousy, Bill Sharman, Tom Heinsohn, Sam Jones, K.C. Jones and John Havlicek all wore the green during the dynasty.

11Titles won by Bill Russell as a player

The arithmetic of the era is staggering. Between 1957 and 1969 the Celtics appeared in 12 Finals and lost only one. Much of that success came at the expense of the Lakers, first in Minneapolis and then in Los Angeles, a pattern that would define the league’s defining rivalry for generations.

Cowens, Havlicek and the 1970s bridge

Russell’s retirement might have ended lesser organizations, but Boston reloaded. Behind the fiery center Dave Cowens and the ageless Havlicek, the Celtics claimed two more titles in the 1970s. The 1974 crown came against Kareem Abdul-Jabbar and the Milwaukee Bucks in a seven-game struggle, with Havlicek named Finals MVP.

The 1976 championship is remembered above all for Game 5 against the Phoenix Suns, a triple-overtime classic often cited as one of the greatest games ever played. Jo Jo White earned Finals MVP honors as Boston closed out the series in six. These titles are sometimes overlooked between the glamour of the Russell and Bird years, but they kept the championship culture intact through a period of transition.

Bird, McHale and Parish: the 1980s renaissance

The arrival of Larry Bird in 1979 began a third golden age. Paired with Kevin McHale and Robert Parish in one of the finest frontcourts the league has seen, Bird led Boston to titles in 1981, 1984 and 1986. The 1981 win over the Houston Rockets announced the new era. The 1984 Finals, a seven-game war against Magic Johnson’s Lakers, revived the old rivalry for a national television audience and helped power the league’s commercial boom.

The 1986 team, which added Bill Walton off the bench, is frequently ranked among the strongest single-season sides in NBA history. Bird collected Finals MVP awards in both 1984 and 1986, and the trio of Bird, McHale and Parish anchored a side that balanced skill, toughness and basketball intelligence.

The long wait and the 2008 reward

After 1986 came the longest drought in franchise history. Injuries, the tragic early deaths of Len Bias and Reggie Lewis, and years of rebuilding kept Boston out of contention. The breakthrough arrived in 2008, when general manager Danny Ainge assembled a new “Big Three” by pairing franchise cornerstone Paul Pierce with Kevin Garnett and Ray Allen.

That side, coached by Doc Rivers and built on a ferocious defensive identity, beat the Lakers 4-2 to deliver banner number 17. Pierce was named Finals MVP after averaging 21.8 points, 4.5 rebounds and 6.3 assists across the series. The title ended a 22-year wait and put Boston a championship ahead of the Lakers, who had 16 titles at the time.

2024: the record-breaking 18th banner

The most recent championship carried historical weight beyond its own merits. Built patiently around two drafted wings, Jayson Tatum and Jaylen Brown, Boston produced a dominant campaign and swept through the postseason with only three losses. In the Finals they dispatched the Dallas Mavericks in five games under head coach Joe Mazzulla.

Brown was named Finals MVP, averaging 20.8 points, 5.4 rebounds and 5.0 assists. The win pushed the Celtics to 18 titles, widening their lead over the Lakers and cementing Boston’s hold on the record for most NBA championships.

What the banners add up to

Measured by trophies, the Celtics sit at the summit of the NBA. Measured by context, their claim is stronger still: the eight-in-a-row record is untouchable in the modern game, Russell’s 11 rings are beyond any individual’s reach, and the Lakers rivalry has produced more Finals drama than any other matchup in the sport. Each of the four championship eras could stand alone as a proud franchise history. Together they form the deepest trophy case basketball has produced, and the 2024 title ensured that, for now, no one can claim to have won more.
