The 2012–13 season was the 114th season of competitive league football in the history of English football club Wolverhampton Wanderers. The club competed in the second tier of the English football system, the Football League Championship. They had returned to the second level having been relegated from the Premier League after three seasons during the previous season.

Norwegian manager Ståle Solbakken was appointed to begin the season as the club's manager, but he was sacked on 5 January with the team in 18th place and having been eliminated from the FA Cup by a non-league club. He was swiftly replaced by former Doncaster Rovers manager Dean Saunders who oversaw the remaining twenty games.

After Saunders failed to bring any upturn, the club suffered relegation for a second successive season to drop into the third level for the first time since 1988–89. This made them the only club to twice experience back-to-back relegations from the top flight, having already suffered this previously in the mid 1980s. Three days after their relegation was confirmed, Saunders was fired having held the post for only four months.

Having been relegated from the Premier League after three seasons, the club sought to put a new playing style in place under new manager Ståle Solbakken who officially became the permanent replacement for Mick McCarthy on 1 July. In contrast to McCarthy's preference for British and Irish players, the Norwegian used the foreign market for all of his summer signings, with Bakary Sako,Razak Boukari,Björn Sigurðarson and Georg Margreitter signing permanent deals as well as the loan captures of Tongo Doumbia and Sławomir Peszko. Despite these incomings, the transfer window saw the sale of several key players with leading goalscorer Steven Fletcher exiting for a club record £14 million fee, and both Matt Jarvis and Michael Kightly also remaining in the Premier League with new clubs.
