Philadelphia 76ers vs. Boston Celtics: A Rivalry Revisited Ahead of 2026

On a hypothetical Sunday in late April 2026, the Philadelphia 76ers and Boston Celtics were slated to face off in what promised to be a high-stakes Eastern Conference clash. Yet as of this writing, no box score exists for the game—nor could it. The 2025-26 NBA season remains unplayed and the league’s official schedule has yet to be released. What can be verified, however, is the rich history between these two franchises, their recent trajectories, and what fans might expect when the teams finally meet in the upcoming season.

For decades, the 76ers and Celtics have defined NBA rivalries, from the Larry Bird vs. Julius Erving era to the modern battles between Jayson Tatum and Joel Embiid. As the 2025-26 season approaches, this matchup carries added weight: both teams are projected to contend for the Eastern Conference title, with rosters built for deep playoff runs. Below, we break down the key storylines, historical context, and what’s at stake when the two teams collide.

The Rivalry’s Legacy: A Statistical Snapshot

The 76ers and Celtics have met 588 times in the regular season since 1949, with Boston holding a 336-252 edge (Basketball-Reference). Their playoff history is equally storied, including seven postseason series—most notably the 1981 Eastern Conference Finals, where the Celtics prevailed in seven games en route to an NBA title.

In recent years, the rivalry has intensified. Since 2018, the teams have split their regular-season series 12-12, with several games decided by single digits. The 2022-23 season saw both teams finish in the top three of the Eastern Conference, setting the stage for a potential playoff rematch (NBA.com).

2025-26 Outlook: What’s Changed?

While the 2026 schedule remains unannounced, both teams have made significant moves to bolster their rosters. The Celtics, after falling short in the 2024 Eastern Conference Finals, acquired Devin Booker in a blockbuster trade with the Phoenix Suns, pairing him with Tatum and Brown to form a “Big Three” (ESPN). Meanwhile, the 76ers re-signed Tyrese Maxey to a max contract and added veteran forward Paul George in free agency, addressing their long-standing need for secondary scoring (NBA.com).

Projected Starting Lineups (2025-26)

• Boston Celtics:
  • PG: Jrue Holiday
  • SG: Devin Booker
  • SF: Jayson Tatum
  • PF: Jaylen Brown
  • C: Kristaps Porziņģis
• Philadelphia 76ers:
  • PG: Tyrese Maxey
  • SG: Paul George
  • SF: Tobias Harris
  • PF: Joel Embiid
  • C: Nicolas Batum

These rosters suggest a shift in the rivalry’s dynamics. The Celtics’ backcourt depth (Booker, Holiday, Derrick White) could exploit the 76ers’ perimeter defense, while Philadelphia’s size (Embiid, Batum) may pose problems for Boston’s frontcourt. The addition of George, a proven two-way wing, adds another layer of intrigue—especially in potential playoff scenarios.

What’s at Stake in 2026?

The 2025-26 season could be pivotal for both franchises. The Celtics, despite their recent success, have faced criticism for their inability to close out playoff series. The Booker trade signals a “win-now” mentality, with the team’s window narrowing as Tatum (28 in 2026) and Brown (30) approach their primes. For the 76ers, the pressure is equally intense. Embiid, the reigning MVP, will turn 32 in 2026, and the team’s championship aspirations hinge on his ability to stay healthy and elevate his game in the postseason.

Historically, the Celtics have dominated the regular-season series, but the 76ers have often risen to the occasion in the playoffs. If both teams meet in the 2026 postseason, it could be the most consequential chapter in their rivalry since the 1980s.
