2024–25 Cleveland Cavaliers season

The 2024–25 Cleveland Cavaliers season was the 55th season for the franchise in the National Basketball Association (NBA). On May 23, 2024, the Cavaliers fired their head coach J. B. Bickerstaff after five seasons with the team. On June 28, 2024, the Cavaliers hired Kenny Atkinson as their new head coach. The Cavaliers began their regular season with a 15-game win streak; it became the 4th time in NBA history a team has started the regular season with a 15–0 record, joining the 1948–49 Washington Capitols, 1993–94 Houston Rockets, and 2015–16 Golden State Warriors as the only teams to start out either similarly or better than that. This also tied the record for longest winning streak in franchise history, as well as setting the longest winning streak in a head coach's first season with a new team. The Cavaliers clinched a playoff berth on March 5, following a 112–107 victory over the Miami Heat, and clinched the Central Division title on March 11 with a 109–104 win over the Brooklyn Nets. It marked the first time that the Cavaliers won a division title without LeBron James on their roster since 1976 in addition to being their first division title overall since 2018. The Cavaliers broke their record-tying franchise winning streak record from earlier in the season on March 14, with their 16th consecutive victory over the Memphis Grizzlies. On April 8, 2025, following a 135–113 win over the Chicago Bulls, the Cavaliers clinched the #1 seed in the East for the first time since 2016, and the first time without James on their roster.

In the first round of the playoffs, the Cavaliers matched up with the eighth-seeded Miami Heat; Cleveland swept the Heat in dominant fashion, moving on to face the Indiana Pacers in the second round, who would upset them in five games, ending their season in the second round for the second straight season.
