The 2020–21 season was the 143rd year in existence of West Bromwich Albion and their first season back in the Premier League after a two-year absence, following promotion from the Championship in the previous season. They also participated in the FA Cup and the EFL Cup. On 16 December 2020, Albion parted company with head coach Slaven Bilić, after winning one of the first 13 league games. Sam Allardyce was confirmed as his successor later that day, with the former England manager taking charge of his eighth Premier League club, a competition record.
