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.
West Brom were relegated back to the Championship, after just one season in the Premier League, following an away defeat to Arsenal on 9 May 2021. This equalled Norwich City's record of five Premier League relegations and was the first time that a team managed by Sam Allardyce had been relegated from the top flight.
