2025–26 Milwaukee Bucks season

The 2025–26 Milwaukee Bucks season is the 58th season for the franchise in the National Basketball Association (NBA). This is the Bucks first full season since the 2012–13 season that Khris Middleton was not on the roster, for first time since the 2017–18 season that Pat Connaughton and Brook Lopez were not on their opening day roster, and for first time since the 2022–23 season that Damian Lillard was not on the opening day roster. Middleton was traded to the Washington Wizards during the 2024-25 midseason for Kyle Kuzma, whereas Connaughton was traded to the Charlotte Hornets and Lopez signed with the Los Angeles Clippers. Following the Bucks' shocking decision to waive Lillard, he returned to his old team, the Portland Trail Blazers, although it has been confirmed he would be missing the entire season due to rehabilitation on his torn Achilles.

For the first time, the Bucks did not play in the NBA Cup knockout round as they were eliminated by the New York Knicks on November 28, having made 2 consecutive trips to Las Vegas in the past seasons.

The Bucks began the year on a promising 5-2 start, but suffered a 7-game losing streak in November following a groin strain suffered by Giannis Antetokounmpo. After 3 games in his return, Antetokounmpo suffered a calf strain in a game against the Detroit Pistons and would be ruled out indefinitely. Ironically, the injury occurred at a similar time to trade rumours around the former MVP after he had deleted all social media content related to his Bucks tenure. Nonetheless, Milwaukee ended up keeping Antetokounmpo on the roster at the end of the trade deadline, though they would trade away Cole Anthony and Amir Coffey at the deadline in exchange for Nigel Hayes-Davis and Ousmane Dieng.
