Fabio Quagliarella (Italian pronunciation: [ˈfaːbjo kwaʎʎaˈrɛlla]; born 31 January 1983) is an Italian former professional footballer who played as a forward.

Throughout his career, Quagliarella played for eight different Italian clubs, winning three consecutive Serie A titles from the 2011–12 to 2013–14 seasons with Juventus. With the Turin-based club, he also won two Supercoppa Italiana titles in 2012 and 2013, as well as winning the 2002–03 Serie C2 with Fiorentina. In the Italian top flight, Quagliarella also represented Torino, Ascoli, Udinese, Napoli and Sampdoria.

At the international level, Quagliarella represented Italy from under-18 to under-21 youth levels before his debut for the senior team in 2007. He was part of Italy's squads for UEFA Euro 2008, the 2009 FIFA Confederations Cup and the 2010 FIFA World Cup.

Individually, Quagliarella was awarded the Serie A Goal of the Year in 2009, achieved during his time at Udinese; in 2017 and 2018 respectively, he obtained the Premio Gentleman Fairplay and the Scirea Career Award while playing for Sampdoria, which pertain to both personality and playing ability. During the 2018–19 season while at Sampdoria, he scored in eleven consecutive league games, a feat only previously accomplished by Gabriel Batistuta; Quagliarella finished the campaign with 26 goals in Serie A, which saw him capture the Capocannoniere title as the league's top scorer, also being named the league's best forward.

Quagliarella grew up in the youth ranks of Gragnano, then Torino, where he made his debut in Serie A on 14 May 2000, in a 2–1 victory over Piacenza.

In 2002, given his limited playing opportunities, Quagliarella was sent on loan to Fiorentina, at that time in Serie C2. In Florence, he scored just one goal in 12 games. In January, head coach Alberto Cavasin decided to cease the loan, whereupon Torino then sent him on loan to Chieti in Serie C1. He also remained in Abruzzo the following season and scored 17 goals in 32 games during the 2003–04 Serie C1 season. His time in Chieti ended with a total of 19 goals in 43 games; at the end of the season, he returned to Torino, in given the 2004–05 season in Serie B.

At Torino, Quagliarella was an occasional starter, and with seven goals in 34 games, contributed to the club's promotion to Serie A. However, as a result of the bankruptcy of Torino Calcio, in August 2005, he was released on a free transfer and accepted a contract with Ascoli. With Ascoli, he was ensured a starting spot in the lineup during the 2005–06 season, scoring his first goal in Serie A on 21 December 2005, a 1–0 home win over Treviso.

Quagliarella signed with Udinese in the summer of 2005. However, Udinese immediately sold half of his registration rights to newly promoted Ascoli as part of a co-ownership deal. He stayed at Ascoli for just one season, scoring just three times in 33 appearances, and his rights were bought back in full by Udinese in June 2006 for an undisclosed fee.
