The 2009–10 season was the 111th season of competitive league football in the history of English football club Wolverhampton Wanderers. This season saw the club return to the Premier League after a five-year absence. They had won promotion in the previous season as champions of the Football League Championship. Although this season was the club's 61st at the top level of English football, it was only their second season in the modern Premier League; their only previous Premier League campaign had ended in relegation in 2003–04.
