The 2022–23 Boston Celtics season is the 77th season in the National Basketball Association (NBA). The Celtics are coming off of a loss to the Golden State Warriors in six games in the 2022 NBA Finals the season prior. In the offseason, head coach Ime Udoka was suspended for the entire season (officially until June 30, 2023) for a violation of the team's code of conduct after it was revealed that Udoka had engaged in an alleged affair relationship with a female Celtics staff member. Joe Mazzulla was named interim head coach on September 22, 2022.
