Some sports activities rivalries are everlasting, as a consequence of components of geography or shared historical past. Yankees vs. Purple Sox. Military vs. Navy. North Carolina vs. Duke.
But, others wax and wane in context. As an example, the Chicago Bulls and Detroit Pistons had arguably the NBA’s greatest rivalry throughout one of many league’s greatest eras; they battled within the playoffs yearly from 1988 by way of 1991, the final three conferences coming within the convention finals.
However Chicago and Detroit have only one playoff matchup prior to now 35 years, and so they have not each reached the postseason in the identical season since 2008-09. It is tough for a rivalry to maintain its depth with out common playoff kindling.
In an ever-changing league, then, it is value surveying the present rivalry panorama. After a postseason and offseason that elevated a number of the feistiest conflicts round, listed below are the NBA’s prime 10 rivalries coming into the 2026-27 season.
Bounce to the highest 5
Our checklist ideas off with one of many strangest NBA rivalries, as a result of most of the first staff’s followers nonetheless adore the second staff’s greatest participant. However after the Luka Doncic blockbuster in 2025, the Mavericks and Lakers might be inextricably linked for the remainder of the 27-year-old future Corridor of Famer’s profession.
Doncic has averaged 37.7 factors in three video games towards the Mavericks since they traded him, and the Lakers are 3-0 in these contests.
Add within the presence of Cooper Flagg, Dallas’ new younger star, who’s now surrounded by so a lot of Doncic’s former operating mates (Kyrie Irving, P.J. Washington, Daniel Gafford and so forth), and each assembly between these two groups might be a spectacle for the foreseeable future.
9. Cavs proprietor Dan Gilbert vs. Suns proprietor Mat Ishbia
The Cleveland Cavaliers’ and Phoenix Suns’ house owners each run Michigan-based mortgage firms, and that enterprise rivalry has carried over to the NBA. The board of governors’ vote to permit Ishbia to purchase the Suns was unanimous, however with one abstention: Gilbert.
“He would not like me and I do not like him,” Ishbia stated about Gilbert on Invoice Simmons’ podcast in 2023.
Whether or not coincidental or not, the Suns and Cavaliers have not made a commerce within the three-plus years since Ishbia purchased the previous. (The 2 franchises’ final deal, based on Basketball Reference’s commerce tracker, despatched Shaquille O’Neal to Cleveland again in 2009.)
From a purely stylistic perspective, that is the most effective particular person rivalry within the NBA proper now: the most effective offensive huge man in a long time versus a participant with an opportunity to grow to be the most effective defensive huge man ever.
For probably the most half, Jokic has had Wembanyama’s quantity to this point. He has scored a whopping 37.3 factors per sport in seven conferences, together with a minimum of 40 in every of the previous three. However Wembanyama is 9 years Jokic’s junior, in order that steadiness may begin tilting within the different route quickly.
The 2 All-NBA facilities’ solely showdown final season confirmed exactly why their particular person duels are so thrilling. In an additional time contest in April, Wembanyama tallied 34 factors, 18 rebounds, seven assists and 5 blocks — just for Jokic to one-up him with 40 factors, 13 assists and three blocks, together with an impressive Sombor shuffle over his rival to assist clinch the win.

Boston and Miami have probably the most playoff matchups — seven — between any two groups within the twenty first century, based on ESPN Analysis.
These battles got here in two flurries, a decade aside. The Celtics and Warmth met within the 2010, 2011 and 2012 postseasons, then took a while off and reengaged their rivalry within the 2020, 2022, 2023 and 2024 playoffs. Three of these sequence went the complete seven video games, and 4 got here within the convention finals.
Remarkably, the groups’ general document in these seven playoff sequence is even: 21 wins for Boston, 21 for Miami. And with Giannis Antetokounmpo now a member of the Warmth — after three playoff sequence of his personal as a Milwaukee Buck towards Boston — there may be much more star energy on this rivalry. It is no marvel that Boston and Miami are slated to play on Christmas afternoon this season.
James and Curry have been on the peak of their powers when their rivalry started on the daybreak of the Warriors’ dynasty in 2015, however the two are not fairly at that stage. James will have fun his forty second birthday throughout this upcoming season, and Curry will flip 39.
But a decade after they dueled in 4 straight Finals, each matchup between the 2 future Corridor of Famers remains to be must-see TV. They’re nonetheless gifted sufficient — each have been deserving All-Stars final season — to entertain, and there is merely a lot historical past infused in all their conferences. Each time James beckons Curry into an isolation, and each time Curry pulls up for a 3-pointer over James’ outstretched hand, it brings again the reminiscences of so many high-stakes pictures between the 2 defining gamers of this period.
Their rivalry good points religious bonus factors as a result of it has remodeled right into a friendship over time, peaking with a gold medal as James and Curry teamed up on the 2024 Olympics.
That is the lively rivalry that’s most rooted in nostalgia. The 2 winningest NBA franchises have 12 playoff conferences throughout three eras of basketball historical past (Russell vs. West, Chook vs. Magic, Pierce vs. Kobe), however simply two for the reason that Nineteen Eighties.
It is tough, after all, for groups in separate conferences to fulfill recurrently within the playoffs — particularly within the present period of parity, the place it is uncommon for any staff to make a number of Finals journeys in shut succession. Each Boston and Los Angeles seem like second-tier contenders coming into the 2026-27 season, making it unlikely the 2 groups will attain the Finals anytime quickly and face off for the primary time since 2010.
That lack of consistency means Celtics vs. Lakers is not the most effective lively rivalry within the NBA. However this rivalry’s pageantry and historical past are so nice — the “Beat L.A.” chants so deafening, the published’s outdated spotlight reels so inspiring — that it nonetheless warrants a wholesome placement on this checklist.
This rivalry began with Reggie Miller on one facet and Patrick Ewing and Spike Lee on the opposite, because the Pacers and Knicks met six occasions in eight postseasons from 1993 by way of 2000. That run produced a bunch of memorable moments, from Miller’s choke pantomime and eight factors in 9 seconds, to Larry Johnson’s four-point play.
Then it hibernated for some time; between 2000 and 2024, the 2 Japanese foes performed solely as soon as within the postseason, when the Pacers eradicated the most effective staff of the Knicks’ Carmelo Anthony period in 2013.
However Tyrese Haliburton, Jalen Brunson and their teammates have rekindled a superb rivalry. The Pacers eradicated the Knicks in Sport 7 of the Japanese Convention semifinals at Madison Sq. Backyard in 2024, then upset the Knicks once more within the convention finals to achieve the Finals in 2025 — a sequence that featured a momentous comeback and Haliburton’s homage to Miller’s choke signal.
Each fanbases can level to accidents to downplay the opposite’s accomplishments. A Knicks devoted would possibly say that Indiana solely gained in 2024 as a result of New York’s roster was so injured; Pacers followers would possibly contend that the Knicks’ title run was potential as a result of Haliburton’s proper Achilles tear meant New York did not have to fret about them within the postseason.
That back-and-forth chatter serves to intensify this rivalry, which ought to recommence with Haliburton wholesome this season and each groups angling to return to the Finals.

Many of the groups on this checklist are the NBA’s most traditionally profitable franchises — which is smart, as a result of extra deep playoff runs over a long time means extra alternatives for high-stakes clashes that fire up dangerous blood.
That is not the case for Denver and Minnesota, two franchises with a complete of 1 Finals look between them. However they’ve stirred up sufficient latest drama — by way of playoff showdowns in 2023, 2024 and 2026, in addition to a 2018 de facto playoff tiebreaker that went to additional time on the final night time of the common season — to warrant sturdy placement on this checklist nonetheless.
This rivalry has nearly the whole lot, from immense star energy to forcing particular person matchups — most notably Rudy Gobert’s efforts to protect Jokic — to a wholesome dislike between locker rooms. “They’re all dangerous defenders,” Timberwolves wing Jaden McDaniels taunted throughout the 2026 playoffs.
The Timberwolves have the higher hand for now: Minnesota eradicated the defending champion Nuggets in 2024 and superior — regardless of a number of accidents — previous their rivals in 2026. However Minnesota made dramatic modifications to its roster this offseason, and each groups at the moment are chasing the subsequent two groups on this checklist slightly than one another.
These two southwestern giants have met in 4 playoff sequence for the reason that Thunder moved from Seattle, and all 4 have been memorably aggressive:
-
Within the 2012 convention finals, the Spurs took a 2-0 lead — as a part of a 20-game profitable streak — earlier than the Thunder gained 4 video games in a row.
-
Within the 2014 convention finals, the Spurs gained Sport 6 in additional time to achieve the Finals.
-
Within the 2016 second spherical, the Thunder upset a Spurs staff that had gained a franchise-record 67 video games within the common season; the Spurs had a 42-1 document at dwelling that season earlier than dropping twice towards the Thunder in San Antonio.
-
Within the 2026 convention finals, the Spurs eradicated the defending champs in Sport 7 in Oklahoma Metropolis.
That final sequence propelled this rivalry to a fair higher stage, after an everyday season by which the Thunder began 24-1 solely to drop three video games to the Spurs in 13 days. Each groups have electrical younger backcourts, and Wembanyama and Chet Holmgren have been fierce rivals ever since they dueled on the worldwide youth scene.
This rivalry has a robust case for the No. 1 spot proper now, and since each Oklahoma Metropolis and San Antonio venture to stay among the many NBA’s title favorites for seasons to return, they’re prone to maintain including to that checklist of memorable playoff sequence.
Their subsequent battle, although, comes as quickly as potential when the Thunder make a journey to San Antonio on opening night time.
The Celtics and 76ers are probably the most frequent playoff rivals all through NBA historical past. The 2 franchises have met in 23 playoff sequence all time, which is nicely forward of the second-most-frequent matchup (15 conferences between the Knicks and Celtics).
However in latest seasons the rivalry appeared to be fading as a result of it had grown so one-sided: Till this spring, the 76ers hadn’t eradicated Boston since 1982. On the opposite facet of the ledger, the Celtics knocked out Philadelphia in 1985, 2002, 2012, 2018, 2020 and 2023.
That modified this previous season, nonetheless. First, the 76ers got here again from a 3-1 deficit within the first spherical to stun the Celtics, who have been favored not solely to beat Philadelphia once more, however to return to the Finals. Then, the 76ers traded for longtime Celtic Jaylen Brown, a former Finals MVP for Boston. And eventually, they signed James in free company.
These transactions particularly add fascinating wrinkles to an already heated rivalry. Presumably, when the 2 groups meet this season, Brown and Jayson Tatum will spend loads of time guarding one another as teammates turned rivals. James additionally folds in his personal prolonged particular person rivalry with the Celtics, whom he confronted in playoff sequence in 2008, 2010, 2011, 2012, 2015, 2017 and 2018; the NBA’s all-time scoring chief skilled arguably the most effective and worst moments of his profession towards Boston within the playoffs.
In the end, the NBA’s most frequent rivalry is as soon as once more its fiercest, as nicely.
