The 2023–24 season was Port Vale's 112th season of football in the English Football League (EFL), and their second consecutive season in League One. The season covered the period from 1 July 2023 through to 30 June 2024. It is managerAndy Crosby's first full season in charge of the club.
Nine permanent and four loan signings were made to replace the eleven players sold or released in the summer transfer window. Only four of the new arrivals started on the opening day 7–0 defeat at Barnsley, in what was the biggest opening day defeat for any team in the EFL in 60 years. The team recovered confidence immediately, however, winning ten of the remaining available twelve points in August and progressing into the third round of the EFL Cup. The winning run extended to four games in the league, and although Vale progressed into the fourth round of the EFL Cup, they missed the opportunity to go top of the table in mid-September. Injuries then took their toll as Vale took only one point from five league games in October, though they continued their progress in the EFL Cup, beating Mansfield Town to reach the quarter-final stage for the first time in the club's history. However, the club's winless run in the league continued into eleven games.
