Giovanni Vavassori (born January 16, 1952 in Arcene, Bergamo) is an Italian football manager and former centre back, currently in charge with Serie B side Cesena.
In 2004, Vavassori was appointed head coach of Serie B team Ternana, but resigned two weeks later citing falling-out with his players.
In 2005, Vavassori was signed by Serie C1 club Genoa, with the goal to lead the grifone back to Serie B. He was however sacked later and replaced by Attilio Perotti, and then reappointed at Perotti's place; after ending the regular season in second place, Genoa then won the promotion playoffs under Vavassori and achieved promotion to Serie B.
On April 18, 2007 Giovanni Vavassori was appointed at the helm of U.S. Avellino, another Serie C1 club, to fill the position left vacant by the sacking of Giuseppe Galderisi. In his tenure at Avellino, Vavassori was not able to overtake first-placed Ravenna, ending the regular season with a second place; however, he was able to lead the biancoverdi to win the promotion playoff and achieve his second consecutive Serie B promotion. Originally confirmed as Avellino boss also for their 2007-08 Serie B campaign, Vavassori surprisingly tended his resignations on July 16, 2007. However, Vavassori found a Serie B job just a few months later, as he was appointed as Cesena boss on November 12, replacing Fabrizio Castori.. On February 25, 2008, following a 0–3 home loss to AlbinoLeffe, Vavassori was dismissed from his role as Cesena's manager.
