===Boston Celtics===
During the early 2000s, the Nets were led by [[Jason Kidd]] and [[Kenyon Martin]], while the [[Boston Celtics]] were experiencing newfound success behind Paul Pierce and Antoine Walker. The rivalry began to heat up in the conference finals of the [[2002 NBA playoffs|2002 playoffs]], which was preceded by [[trash talk]]ing from the Celtics,<ref>{{cite news | url=http://articles.nydailynews.com/2002-05-20/sports/18200319_1_antoine-walker-kenyon-martin-paul-pierce | location=New York | work=Daily News | title=Celtics Talk A Good Game&nbsp;– New York Daily News | first1=Ohm | last1=Youngmisuk | first2=Darren | last2=Everson | date=May 20, 2002 | access-date=April 13, 2011 | archive-date=March 8, 2012 | archive-url=https://web.archive.org/web/20120308073957/http://articles.nydailynews.com/2002-05-20/sports/18200319_1_antoine-walker-kenyon-martin-paul-pierce | url-status=dead}}</ref> who claimed Martin was a "fake" tough guy. Things progressed as the series started, and on-court tensions seemed to spill into the stands. Celtic fans berated Kidd and his family with chants of ''"Wife Beater!"''<ref>{{cite web |author=Steve WilsteinAP Sports Writer |url=http://amarillo.com/stories/053102/spo_jasonkidd.shtml |title=Celtics fans' taunts hurt Jason Kidd's wife &#124; Amarillo.com &#124; Amarillo Globe-News |publisher=Amarillo.com |date=May 31, 2002 |access-date=October 16, 2013 |archive-url=https://web.archive.org/web/20131019040927/http://amarillo.com/stories/053102/spo_jasonkidd.shtml |archive-date=October 19, 2013 |url-status=dead}}</ref> in response to Kidd's 2001 domestic abuse charge. When the series returned to New Jersey, Nets fans responded, with some brandishing signs that read "Will someone please stab Paul Pierce?"<ref>{{cite web |url=http://www.enquirer.com/editions/2002/05/31/spt_nets_celtics_heating.html |title=Nets, Celtics heating it up |publisher=Enquirer.com |date=May 31, 2002 |access-date=October 16, 2013 |archive-date=October 17, 2019 |archive-url=https://web.archive.org/web/20191017200834/https://www.cincinnati.com/ |url-status=live}}</ref> referring to a night club incident in 2000 in which Pierce was stabbed 11 times. When asked about the fan barbs being traded, [[Kenyon Martin]] stated, "Our fans hate them, their fans hate us." [[Bill Walton]] said at the time that Nets–Celtics was the "beginning of the next great NBA rivalry" during the conference finals. Led by Kidd, the Nets advanced to the [[2002 NBA Finals|NBA Finals]], and the following year, swept Boston in the [[2003 NBA playoffs|2003 playoffs]].

On November 28, 2012, there were indications that the rivalry might be rekindled when an altercation occurred on the court, resulting in the ejection of [[Rajon Rondo]], [[Gerald Wallace]], and [[Kris Humphries]]. Rondo was suspended for two games in the aftermath, while Wallace and [[Kevin Garnett]] were fined.<ref>{{cite news | url=https://www.nytimes.com/2012/11/30/sports/basketball/celtics-rajon-rondo-suspended-2-games-for-melee.html?_r=0 | work=The New York Times | title=Suspension and 2 Fines After Brawl | first1=May | last1=Peter | date=November 30, 2012 | access-date=February 6, 2017 | archive-date=November 8, 2017 | archive-url=https://web.archive.org/web/20171108035905/http://www.nytimes.com/2012/11/30/sports/basketball/celtics-rajon-rondo-suspended-2-games-for-melee.html?_r=0 | url-status=live}}</ref> The story was revisited on December 25, when Wallace grabbed Garnett's shorts and the two had to be broken up by referees and players alike.

In the 2019 NBA off-season, the Nets signed point guard [[Kyrie Irving]]. Coming off two seasons with the Celtics, Irving was described as selfish by many critics. This impression caused many Celtics fans to blame him for the Celtics' inability to get through to the playoffs.

During a regular season game in the 2019–20 season between the Celtics and Nets, the Celtics' fans displayed their displeasure with Irving by chanting "Kyrie sucks" in [[TD Garden]].<ref>{{cite web |last1=Lewis |first1=Brian |title=Even injured and absent, Kyrie Irving isn't welcome in Boston |url=https://nypost.com/2019/11/27/even-injured-and-absent-kyrie-irving-isnt-welcome-in-boston/ |website=New York Post |access-date=December 11, 2019 |date=November 27, 2019 |archive-date=December 7, 2019 |archive-url=https://web.archive.org/web/20191207005725/https://nypost.com/2019/11/27/even-injured-and-absent-kyrie-irving-isnt-welcome-in-boston/ |url-status=live}}</ref> When the series returned to Brooklyn two days later, the Nets' fans chanted "Kyrie's better" in response to the chants in Boston.<ref>{{cite web |title=Nets fans clap back with 'Kyrie's better' chant with Kemba Walker at line |url=https://www.nbcsports.com/boston/celtics/nets-fans-clap-back-kyries-better-chant-kemba-walker-line |website=NBC Sports Boston |access-date=December 11, 2019 |date=November 29, 2019 |archive-date=December 11, 2019 |archive-url=https://web.archive.org/web/20191211010840/https://www.nbcsports.com/boston/celtics/nets-fans-clap-back-kyries-better-chant-kemba-walker-line |url-status=live}}</ref> The "Kyrie's Better" chants reference to how the Celtics signed [[Kemba Walker]] after Irving left for the Nets.

On May 30, 2021, after Kyrie Irving stomped on the Celtics center-court logo, a fan threw a [[water bottle]] at Irving at TD Garden following a Nets victory and a 3–1 lead in the series.<ref>{{cite web|last1=Andrews|first1=Malika|last2=Bontemps|first2=Tim|title=Boston Celtics fan arrested after allegedly throwing water bottle at Kyrie Irving|url=https://www.espn.com/nba/story/_/id/31540143/boston-celtics-fan-appears-throw-water-bottle-brooklyn-nets-kyrie-irving|website=ESPN.com|access-date=June 1, 2021|date=May 27, 2021|archive-date=March 27, 2022|archive-url=https://web.archive.org/web/20220327092130/https://www.espn.com/nba/story/_/id/31540143/boston-celtics-fan-appears-throw-water-bottle-brooklyn-nets-kyrie-irving|url-status=live}}</ref>
