Flavia Pennetta (born 25 February 1982 in Brindisi, Puglia) is an Italian professional tennis player. She became Italy's first top 10 female player on 17 August 2009. She is also ranked World No. 21 in doubles.

Pennetta has won eight career WTA singles titles, including back-to-back titles in Bogotá and Acapulco in 2005. She and her Italian teammates Mara Santangelo, Francesca Schiavone, and Roberta Vinci beat the Belgium team 3–2 in the 2006 Fed Cup final. Justine Henin had to retire in the fifth and final match due to an injury in her right knee, which let Italy win their first Fed Cup trophy.

Pennetta has defeated multiple Grand Slam singles champions such as Justine Henin, Martina Hingis, Amélie Mauresmo, Venus Williams, Maria Sharapova, and former World No. 1 Jelena Janković. Pennetta is also one of only seven women to beat Williams three consecutive times. In doubles, she reached the 2005 US Open final with her partner Elena Dementieva.
