LeBron James currently wears jersey number 23.
The number has been associated with James since his early professional career, when he chose it as a tribute to Michael Jordan. James wore No. 23 during his first stint with the Cleveland Cavaliers and later returned to it after playing in Miami.
During his four seasons with the Miami Heat, James wore No. 6 and won two championships. He also wore No. 6 with the Lakers from 2019–20 through 2020–21. James switched back to No. 23 in Los Angeles, partly because the NBA retired No. 6 throughout the league in honor of Bill Russell.
After leaving the Lakers for the Philadelphia 76ers in 2026, James retained No. 23. That means the answer is not tied only to one team: he has worn the number with Cleveland, Los Angeles, and Philadelphia. No. 6 is a notable former number, while 32 and 33 have never been his standard NBA jersey number.
