==== 2007–2009: first championship ====
On June 28, 2007, the Sonics traded Allen and [[Glen Davis (basketball)|Glen Davis]], the 35th overall pick in the [[2007 NBA draft]], to the [[Boston Celtics|Celtics]] in exchange for [[Delonte West]], [[Wally Szczerbiak]], and the fifth overall pick, [[Jeff Green (basketball)|Jeff Green]]. Shortly after acquiring Allen, the Celtics acquired [[Minnesota Timberwolves]] forward [[Kevin Garnett]] to play alongside Allen and [[Paul Pierce]].<ref>{{cite web |title=Celtics Acquire 10-Time All Star Kevin Garnett- Celtics.com |website=[[NBA.com]] |url=http://www.nba.com/celtics/news/press073107-garnett.html |access-date=May 7, 2011 |archive-date=May 10, 2012 |archive-url=https://web.archive.org/web/20120510050157/http://www.nba.com/celtics/news/press073107-garnett.html |url-status=live }}</ref> Upon joining the Celtics, Allen changed his jersey to number 20 because [[Paul Pierce]] already had number 34 in Boston.<ref name="ESPN">{{cite web|url=https://www.espn.com/blog/boston/celtics/post/_/id/4696164/allen-reflects-on-celtics-in-heat-intro|title=Allen reflects on Celtics in Heat intro|date=July 11, 2012}}</ref>

On November 4, 2007, Allen passed 17,000 points for his career with his first of two [[Three-point field goal|3-pointers]] in overtime in a 98–95 victory against the [[Toronto Raptors]], in which he sank the game winning 3-pointer with three seconds remaining in overtime.<ref>[https://web.archive.org/web/20160821084658/http://www.espn.com/nba/recap?gameId=271104028 Allen's last-second 3 caps milestone day as C's nip Raps], [[Associated Press]], November 4, 2007.</ref>

On February 13, 2008, Allen was named as the replacement for injured [[Eastern Conference (NBA)|East]] [[NBA All-Star Game|All-Star]] [[Caron Butler]] of the [[Washington Wizards]], who was out with a left hip flexor strain, for the [[2008 NBA All-Star Game]] in [[New Orleans]]. While [[LeBron James]] was given the [[NBA All-Star Game Most Valuable Player Award|All-Star MVP Award]], many analysts, including the [[TNT (U.S. TV network)|TNT]] commentators of the game, felt it should have gone to Allen, who scored 14 points in a stretch of 2 minutes and 30 seconds in the fourth quarter to seal the win for the East team.

On March 28, 2008, Allen was honored as the 3rd best of the 20 greatest players in franchise history during [[Milwaukee Bucks|Milwaukee]]'s ''40th Anniversary Team Celebration'', but could not attend the festivities because of the [[Boston Celtics|Celtics]]' game against the [[New Orleans Hornets]]. The [[Boston Celtics]] finished 66–16, and were the #1 seed in the [[2008 NBA Playoffs]]. The Celtics struggled in the first two rounds of the playoffs, losing every single away game, but maintaining an undefeated playoff record at home. The Celtics had defeated the #8 seeded [[Atlanta Hawks]] 4–3 and then defeated the #4 seeded [[Cleveland Cavaliers]] 4–3 as well. They advanced to the [[2008 NBA Finals]] after a 4–2 Conference finals series win over the [[Detroit Pistons]].<ref name=40years>Charles F.

On June 12, 2008, Allen would play all 48 minutes and contribute greatly with 19 points and 9 rebounds in what would become the largest comeback in NBA Finals history, with the Celtics coming back from a 24-point deficit at one point in the second quarter and a deficit as large as 20 in the third. In that game, Allen would make the game clinching layup with 16.4 seconds remaining to give the Celtics a 5-point lead and put the game away.

On June 17, 2008, in the series-ending [[2008 NBA Finals#Game 6|Game 6]] of the [[2008 NBA Finals|NBA Finals]], Allen tied an NBA Finals record with seven [[Three-point field goal|three-pointers]] in the Celtics' 131–92 victory over the [[Los Angeles Lakers]].<ref>{{cite web |url=http://www.boston.com/sports/basketball/celtics/articles/2008/06/18/allen_takes_care_of_business |title=Allen takes care of business |publisher=Boston.com |date=June 18, 2008 |access-date=March 29, 2012 |archive-date=November 4, 2012 |archive-url=https://web.archive.org/web/20121104002947/http://www.boston.com/sports/basketball/celtics/articles/2008/06/18/allen_takes_care_of_business/ |url-status=live }}</ref> With the victory, Allen secured his first NBA championship.

On February 5, 2009, Allen was named as the All-Star replacement for [[Orlando Magic]] point guard Jameer Nelson. This marked Allen's ninth time on the All-Star team and the second straight year he had made it alongside teammates [[Kevin Garnett]] and [[Paul Pierce]].

On February 22, 2009, with his streak ending at 72, Allen broke the Celtics franchise record in consecutive free throws made previously set by [[Larry Bird]] (71).

In the first round of the 2009 playoffs against the [[Chicago Bulls]], game one proved to be tough for Allen. He ended up shooting 1–11 from the field, and the Celtics lost by two. In game 2 however, Allen nailed the game winning three-pointer at the end of regulation with two seconds left to cap off an impressive 30 point night.<ref>{{cite web |url=http://www.nba.com/games/20090420/CHIBOS/gameinfo.html |title=Bulls at Celtics Game Scoreboard |work=NBA.com |date=April 20, 2009 |access-date=December 29, 2010 |archive-date=June 4, 2011 |archive-url=https://web.archive.org/web/20110604185046/http://www.nba.com/games/20090420/CHIBOS/gameinfo.html |url-status=live }}</ref>  In Game 6, despite a Boston loss, Allen managed to score 51 points. Boston ended up winning the series in 7 Games. He reunited with former teammate and co-captain of the [[Seattle SuperSonics]], [[Rashard Lewis]] in the conference semifinals, that time as opponents, however. After 4 games and a 2–2 series tie, his highest scoring game was a 22-point performance in a Game 2 victory.<ref>{{cite news |url=https://sports.yahoo.com/nba/boxscore?gid=2009050602 |title=Orlando Magic/Boston Celtics Box Score Wednesday May 6, 2009 |work=Yahoo!
