The 2026–27 Boston Celtics season will be the 81st season of the franchise in the National Basketball Association (NBA). This is the first season since 2015–16 that Jaylen Brown is not on the opening day roster, as he was traded to the Philadelphia 76ers on July 1 for Paul George and four future draft picks.

Round Pick Player Position Nationality College 1 27 Chris Cenac PF United States Houston 2 40 Dillon MitchellSFSt. John's The Celtics entered the draft holding their original first-round selection and a second-round selection acquired through a previous trade. The Celtics acquired the latter from the Orlando Magic as part of a trade in 2025, having originated with the Milwaukee Bucks, whose unfavorable record in the 2025–26 NBA season ensured the pick's conveyance. The Celtics had also traded away their original second-round pick to the Atlanta Hawks as part of the 2025 Kristaps Porziņģis three-team trade, conveying as the less favorable selection after finishing with a better record than the Memphis Grizzlies.
