Here is the list of three teams that have been relegated from the EFL Championship in 2025 (2024/25 season) to League One, and will therefore be playing in the English third tier for the upcoming 2025/26 season.
Which teams were relegated from the Championship at the end of the 24/25 season?
Luton Town, Plymouth Argyle and Cardiff City were relegated from the EFL Championship at the end of the 2024-25 season.
