Eighteen. That is the number everyone in Boston lives and breathes. When you walk into the TD Garden and look up at the rafters, the sheer volume of white and green banners is almost overwhelming. It’s a lot. Most franchises dream of just one parade, one night of champagne showers, and one ring. The Celtics? They’ve turned it into a century-long habit.
If you are trying to track exactly what years did the Boston Celtics win the championship, you’re basically looking at a timeline of NBA history itself. They didn't just win; they dictated how the game was played across multiple eras. From the grainy black-and-white days of the 1950s to the high-definition glory of 2024, the hardware has stayed consistent.
The Dynasty That Shouldn't Have Been Possible
It started in 1957. Red Auerbach was the mastermind behind the bench, a man known for his victory cigars and a temper that could melt ice. This first title was the spark. They beat the St. Louis Hawks in a grueling seven-game series that went to double overtime in the final game. Imagine the tension. One shot goes the other way, and maybe the "Mystique" never even starts.
Then came the run. The absolute, soul-crushing dominance.
Starting in 1959, the Celtics won eight straight titles. Let that sink in for a second. Eight years in a row, no one else even touched the trophy. This wasn't just luck. It was Bill Russell. Russell wasn't the greatest scorer—guys like Wilt Chamberlain had him beat there—but he was the greatest winner. He anchored a defense that made opponents feel like they were playing in a phone booth.
The specific years during this insane stretch were 1959, 1960, 1961, 1962, 1963, 1964, 1965, and 1966. Honestly, it’s a bit ridiculous when you see it written out like that. Most modern fans complain if their team doesn't win twice in a decade. These guys owned the entire sixties.
After a brief one-year "break" where the 76ers took the crown, the Celtics came right back. They grabbed two more in 1968 and 1969. By the time Russell retired, he had 11 rings. Eleven. He has more rings than he has fingers. It's the kind of stat that feels like a typo, but it’s 100% cold, hard fact.

Transitioning into the Cowens and White Era
People often forget the 70s. Everyone talks about the Russell era or the Bird era, but the middle child of the Celtics' history was actually pretty successful too. After Russell left, there was a brief identity crisis. But then came Dave Cowens—a ginger-haired whirlwind of energy—and Jo Jo White.
They weren't a dynasty in the same sense as the 60s, but they were tough as nails. In 1974, they took down Kareem Abdul-Jabbar and the Milwaukee Bucks. It was a clash of styles. Two years later, in 1976, they did it again, winning one of the most famous Finals games in history—a triple-overtime thriller against the Phoenix Suns. If you haven't seen the highlights of that Game 5, go find them. It’s chaotic, beautiful basketball.
The Bird vs. Magic Revolution
Then the 80s hit. This is when the NBA really became a global powerhouse, and it was mostly because of two guys: Larry Bird and Magic Johnson.
The Celtics’ 1981 title felt like a rebirth. Bird was the "Hick from French Lick," a guy who looked like he shouldn't be able to jump over a phone book but could pass and shoot better than anyone on the planet. They beat the Rockets that year. But the real meat of the decade was the rivalry with the Lakers.
In 1984, the Celtics won what many consider the greatest Finals series ever played. It was Bird vs. Magic. East vs. West. It was personal. The heat in the old Boston Garden was so intense during Game 5—the "Heat Game"—that players were literally gasping for air and using oxygen tanks. The Celtics won in seven.
They won again in 1986. That 1986 team? Many basketball historians, like Bill Simmons in The Book of Basketball, argue they were the greatest team to ever lace up sneakers. They went 40-1 at home. They had Bird, Kevin McHale, Robert Parish, Dennis Johnson, and Bill Walton coming off the bench. They were unstoppable.

The Long Drought and the New Big Three
For a long time, the question of what years did the Boston Celtics win the championship ended with 1986. A generation of fans grew up only knowing the stories of their fathers and grandfathers. The 90s were lean. The early 2000s were hopeful but fell short.
Everything changed in the summer of 2007. Danny Ainge, the GM at the time, pulled off two blockbuster trades to bring Kevin Garnett and Ray Allen to Boston to join Paul Pierce. They called them the "Big Three."
The impact was immediate. In 2008, they went from being one of the worst teams in the league to hoisting the Larry O'Brien trophy. They beat the Lakers, which made it even sweeter for the city of Boston. Seeing Paul Pierce limp off the court and return like a hero—whether you believe the "wheelchair" story or not—is a core memory for any Celtics fan.
Modern Glory: Banner 18
For sixteen years, the Celtics hovered near the top. They made deep playoff runs. They went to the Finals in 2010 and 2022. They lost heartbreakers. Fans started to wonder if the "Jays"—Jayson Tatum and Jaylen Brown—could actually get it done. The pressure in Boston is different. If you don't win a title, the season is a failure.
In 2024, they finally silenced the doubters.
This team was a juggernaut. They dominated the regular season. With the additions of Jrue Holiday and Kristaps Porziņģis, they became a defensive nightmare for the rest of the league. They blew through the playoffs and dismantled the Dallas Mavericks in five games. On June 17, 2024—the anniversary of the 2008 title—they officially secured Banner 18, moving past the Los Angeles Lakers for the most championships in NBA history.

Why This Record Matters Today
Knowing what years did the Boston Celtics win the championship isn't just about memorizing dates. It's about understanding the culture of the NBA. The Celtics are the standard. When people talk about "winning pedigree," this is what they mean.
The gap between 1986 and 2008 taught the city patience. The gap between 2008 and 2024 taught them about resilience. Every championship has a different flavor. The 60s were about pure, athletic dominance. The 80s were about grit and high-IQ play. 2024 was about modern spacing and versatile defense.
One thing is certain: they aren't done. With Tatum and Brown in their prime, the front office isn't just looking at the past. They're looking at when the next year gets added to this list.
Actionable Insights for Fans and Historians
If you're looking to dive deeper into this history, don't just look at the scores.
- Watch the 1984 Finals documentary. It captures the Bird-Magic era better than any textbook ever could.
- Research Bill Russell’s player-coach years. In 1968 and 1969, he won those titles while literally coaching the team. It’s a feat we will likely never see again in professional sports.
- Visit the TD Garden museum. If you're ever in Boston, the Sports Museum inside the arena houses actual artifacts from these championship runs, including pieces of the original parquet floor.
- Analyze the 2024 roster construction. For those interested in the "how," looking at how Brad Stevens built the most recent championship team through trades rather than just free agency provides a blueprint for modern NBA management.
