Petra Kvitová (Czech: [ˈpɛtra ˈkvɪtovaː]; born 8 March 1990) is a Czech former professional tennis player. Known for her powerful left-handed groundstrokes and variety, Kvitová won 31 WTA Tour-level career singles titles, including two major titles at Wimbledon in 2011 and 2014. She also won the 2011 WTA Championships, and claimed a bronze medal in singles representing the Czech Republic at the 2016 Rio Olympics. Her career-high ranking of world No. 2 was achieved on 31 October 2011. Kvitová first gained notice by defeating then-world No. 1 Dinara Safina in the third round of the 2009 US Open. This was followed by her first major semifinal appearance at the 2010 Wimbledon Championships. Then, during her breakthrough season in 2011, Kvitová won her first major title at Wimbledon over Maria Sharapova in the final, becoming the first player of either gender born in the 1990s to win a major. At the end of the season, she won the WTA Championships on her debut. She also led the Czech Republic to victory in the Fed Cup that same year, the country's first such title as an independent nation. In 2012, Kvitová reached the semifinals of the Australian and French Opens, and was crowned the US Open Series champion. That same year, she also won the Hopman Cup alongside Tomáš Berdych. In 2014, she won her second major title at Wimbledon, defeating Eugenie Bouchard in the final. In 2015, Kvitová completed the feat of reaching at least the quarterfinals of all four majors after her quarterfinal debut at the US Open. In 2016, she won the WTA Elite Trophy on her debut, thus becoming the first player ever to win both categories of year-end championships on debut. Kvitová was sidelined with injury in the first-half of 2017 following a knife attack during the off-season in 2016. In 2019, she reached her first major final in almost five years, at the Australian Open, finishing runner-up to Naomi Osaka. She retired from the sport in 2025.
