The 2008–09 season was Port Vale's 97th season of football in the English Football League, and first season in League Two, following their relegation from League One. After a poor start to the season manager Lee Sinnott was sacked in September, and was replaced by Dean Glover. Despite a brief period of improvement, Vale then slipped back down the table to finish in eighteenth place. The team were also poor in the cup competitions, exiting the FA Cup at the second round, and both the League Cup and the Football League Trophy at the first round. Marc Richards was the club's top scorer with eleven goals, and goalkeeper Joe Anyon was Player of the Year despite breaking his leg towards the end of the season.

Marc John Richards is an English former professional footballer who played as a striker and is now, upon retiring, a first-team coach at Northampton Town.
