The 1983–84 season was Port Vale's 72nd season of football in the English Football League, and first (15th overall) back in the Third Division following their promotion from the Fourth Division. The club suffered a horrendous start, and John McGrath lost his job before Christmas; he was replaced by his assistant John Rudge. Rudge instigated an immense turnaround in results, but Vale still ended up relegated, six points shy of safety. Ireland international Eamonn O'Keefe was top-scorer and Player of the Year, and young Mark Bright showed his potential, though left at the end of the season.
