2023–24 Chelsea F.C. season

The 2023–24 season was Chelsea Football Club's 118th year in existence and 35th consecutive season in the top flight of English football.

Prior to this season, former Chelsea captain César Azpilicueta left the club at the end of his contract after eleven consecutive seasons, signing for Atlético Madrid in his native Spain. Chelsea academy graduate Reece James replaced him as club captain before the new season opened in July.

Managed by Mauricio Pochettino in his first (and only) season at the club, Chelsea continued to perform below par during the first half of the campaign, vanishing any title hopes. Nevertheless, the club reached the final of the EFL Cup, finishing as runners-up to Liverpool, as well as the semi-finals of the FA Cup. Chelsea ultimately made a marked improvement during the second half of the season, with only one loss in their final fifteen league matches played from February to May. Subsequently, this led the club to finish in 6th place, securing an immediate return to European football for the next season. Despite the improvement in form in the latter half of the season, head coach Mauricio Pochettino left the club by mutual consent on 21 May 2024 after less than one year and one season in charge.
