Marion Bartoli defeated Sabine Lisicki in the final, 6–1, 6–4 to win the ladies' singles tennis title at the 2013 Wimbledon Championships. It was her first and only major title, and she won the title without losing a set, or facing a tiebreak in any set. Bartoli became the first French major champion since Amélie Mauresmo at the 2006 Wimbledon Championships. By winning her first major title on her 47th appearance, she broke the previous women's record of 45, set by Jana Novotná in 1998, for most appearances in majors before winning a title. This was also Bartoli's last major appearance, as she retired from professional tennis the following month. This also made her the first woman to win a Grand Slam at her final appearance since Ann Joneswon Wimbledon in 1969.
Serena Williams was the defending champion, but lost to Lisicki in the fourth round, ending a 34-match winning streak dating back to the Miami Open. It was only her third loss of the season, and her first since Doha. This was the fourth consecutive occasion where Lisicki defeated the reigning French Open champion at Wimbledon, following victories over Svetlana Kuznetsova in 2009, Li Na in 2011, and Maria Sharapova in 2012 (Lisicki did not play at Wimbledon in 2010).
The exits of Li Na and Petra Kvitová in the quarterfinals ensured a first-time major champion. Lisicki was the first German major finalist of either gender since Rainer Schüttler at the 2003 Australian Open, while Bartoli was the first Frenchwoman to contest a major final since herself in 2007. The final marked the second time in the Open Era, after 1998, that neither Wimbledon finalist was a former major champion.
