Along with her elder sister [[Venus Williams|Venus]], Serena Williams was coached by her parents [[Oracene Price]] and [[Richard Williams (tennis coach)|Richard Williams]]. Turning professional in 1995, she won her first major singles title at the [[1999 US Open – Women's singles|1999 US Open]]. From the [[2002 French Open – Women's singles|2002 French Open]] to the [[2003 Australian Open – Women's singles|2003 Australian Open]] she was dominant, winning all four major singles titles (each time over Venus in the final) to achieve both a [[Grand Slam (tennis)#Career Grand Slam|career Grand Slam]] and a [[Grand Slam (tennis)#Non-calendar-year Grand Slam|non-calendar year Grand Slam]] (nicknamed the "Serena Slam"). The next few years saw Williams capture two more major singles titles, but suffer from injury and decline in form. Starting in 2007, however, she gradually returned to form despite continued injuries, reclaiming the world No. 1 singles ranking. Beginning with the [[2012 Wimbledon Championships – Women's singles|2012 Wimbledon Championships]], Williams returned to dominance, claiming [[Tennis at the 2012 Summer Olympics – Women's singles|Olympic gold]] (completing the career Golden Slam in singles)<ref>{{cite web |last=Berkok |first=John |date=August 4, 2020 |title=On This Day: Serena completes her Golden Slam at 2012 London Olympics |url=https://www.tennis.com/news/articles/on-this-day-serena-completes-her-golden-slam-at-2012-london-olympics |access-date=March 28, 2022 |website=Tennis.com |archive-date=April 7, 2022 |archive-url=https://web.archive.org/web/20220407094621/https://www.tennis.com/news/articles/on-this-day-serena-completes-her-golden-slam-at-2012-london-olympics |url-status=live }}</ref> and winning eight out of thirteen singles majors, including all four in a row from 2014–2015 to achieve a second "Serena Slam". At the [[2017 Australian Open – Women's singles|2017 Australian Open]], she won her 23rd major singles title, surpassing [[Steffi Graf]]'s Open Era record. After becoming pregnant, Williams took a break from professional tennis, but reached four major finals upon returning to play. In August 2022, Williams announced her impending "evolution" away from professional tennis, and played her final match at the [[2022 US Open – Women's singles|2022 US Open]].<ref name="New York Times">{{cite news |last1=Streeter |first1=Kurt |title=Serena Williams Will Retire TennisJust as She Played: On Her Own Terms |newspaper=The New York Times |date=August 9, 2022 |url=https://www.nytimes.com/2022/08/09/sports/tennis/serena-williams-retiring-tennis.html |access-date=August 9, 2022 |archive-date=August 9, 2022 |archive-url=https://web.archive.org/web/20220809231005/https://www.nytimes.com/2022/08/09/sports/tennis/serena-williams-retiring-tennis.html |url-status=live }}</ref>

After eight months away from tennis, Williams began her comeback at the [[NASDAQ-100 Open]] in March 2004, where she won the title for the third consecutive year. Although ranked No.7, Williams was seeded second at the French Open, where she lost to Capriati in the quarterfinals. A few weeks later, Williams was seeded first at [[2004 Wimbledon Championships|Wimbledon]], even though her ranking had dropped to No.10. She won six matches en route to the final, where [[Maria Sharapova]] defeated her. The loss caused her to drop out of the top 10 for the first time since 1999. Later that summer, Williams reached her third final of the year at the JPMorgan Chase Open in Los Angeles, where she lost to Lindsay Davenport.

===2016: Equalling the records of Steffi Graf===
{{Main|2016 Serena Williams tennis season}}
Williams was the No.1 seed and defending champion at the [[2016 Australian Open|Australian Open]]. She reached the final without dropping a set, and faced first time Grand Slam finalist [[Angelique Kerber]]. Williams was considered the heavy favorite, as she had never lost an Australian Open final or semifinal. She had also dominated in past matches against Kerber, losing only once to her in six meetings. Williams lost the final in three sets, however, which marked her first-ever three-set loss in the final of a Grand Slam.<ref>{{cite web |last=Mitchell |first=Kevin |date=January 30, 2016 |title=Angelique Kerber stuns Serena Williams to clinch Australian Open title |url=https://www.theguardian.com/sport/2016/jan/30/serena-williams-angelque-kerber-australian-open-final-tennis |url-status=live |archive-url=https://web.archive.org/web/20180621143555/https://www.theguardian.com/sport/2016/jan/30/serena-williams-angelque-kerber-australian-open-final-tennis |archive-date=June 21, 2018 |access-date=June 4, 2018 |website=The Guardian}}</ref><ref>{{Cite news|url=https://www.nytimes.com/2016/01/31/sports/angelique-kerber-upsets-serena-williams-to-win-australian-open.html|title=Angelique Kerber Upsets Serena Williams to Win Australian Open|date=January 30, 2016|work=The New York Times|access-date=June 4, 2018|issn=0362-4331|archive-date=April 6, 2023|archive-url=https://web.archive.org/web/20230406065245/https://www.nytimes.com/2016/01/31/sports/angelique-kerber-upsets-serena-williams-to-win-australian-open.html|url-status=live}}</ref>

The week of February 15 marked Williams's 157th consecutive week ranked No.1, the second-longest streak in WTA history. Only Graf had held the ranking longer, for 186 weeks. Williams competed in [[2016 BNP Paribas Open|Indian Wells]] as the No.1 seed, and reached the final for the first time since 2001. She was defeated by Azarenka, whom she had beaten the last five times the pair had met. This marked the first time since 2004 that Williams lost two consecutive finals. She next played the [[2016 Miami Open|Miami Open]] as the defending champion, losing in the fourth round to Kuznetsova. In Rome, she prevailed over [[Anna-Lena Friedsam]] and [[Christina McHale]] to progress to the quarterfinals, where she defeated Kuznetsova. She then defeated [[Irina-Camelia Begu]] and [[Madison Keys]] to win her 70th career WTA title and her first title of the year.<ref>{{Cite news |last=Rothenberg |first=Ben |date=2016-05-15 |title=At Italian Open, Serena Williams Ends a Long but Lean Drought |url=https://www.nytimes.com/2016/05/16/sports/tennis/serena-williams-madison-keys-italian-open-rome.html |access-date=2024-05-28 |work=The New York Times |language=en-US |issn=0362-4331}}</ref>

At the [[2016 French Open|French Open]], Williams dropped only one set en route to the final, where she faced Muguruza. She lost to the Spanish-Venezuelan player in straight sets, marking the first time she had lost two consecutive Grand Slam finals. At [[2016 Wimbledon|Wimbledon]], Williams again dropped only one set on her way to the final, where she faced Kerber in a rematch of their Australian Open final earlier in the year. Williams defeated Kerber in straight sets and tied Graf's record of 22 Open Era Grand Slam singles titles. Later that day, Williams and her sister won their sixth Wimbledon doubles title and 14th Grand Slam doubles title overall, keeping their perfect record at Grand Slam doubles finals intact.

In July, Williams withdrew from the [[2016 Rogers Cup|Rogers Cup]] due to a shoulder injury.<ref>{{cite web|url=http://www.skysports.com/tennis/news/12040/10511583/serena-williams-withdraws-from-rogers-cup-in-montreal|title=Serena Williams withdraws from the Rogers Cup in Montreal|publisher=[[Sky Sports]]|date=July 24, 2016|access-date=August 24, 2016|archive-date=August 28, 2016|archive-url=https://web.archive.org/web/20160828063813/http://www.skysports.com/tennis/news/12040/10511583/serena-williams-withdraws-from-rogers-cup-in-montreal|url-status=live}}</ref> She next participated in the [[2016 Summer Olympics|Olympics]] in [[Rio de Janeiro]], where she was the defending gold medalist in both singles and doubles, and was the heavy favorite to retain those titles.

===2019: Return to the top 10===
Williams started her 2019 season at the [[2019 Australian Open|Australian Open]], her first appearance at the tournament since winning it in 2017. Seeded 16th, she defeated [[Tatjana Maria]], [[Eugenie Bouchard]], and [[Dayana Yastremska]] in the first three rounds, then bested top seed and world No.1 Halep in the fourth. In the quarterfinals, she met Karolína Plíšková, who won the match after Williams twisted her ankle. This was Williams's earliest defeat at the Australian Open since her fourth-round loss in 2014. Despite the loss, her ranking climbed to No.11. Williams prevailed over Azarenka in the second round of the [[Indian Wells Masters]], but a viral illness caused her to retire. She then experienced a recurrence of a long-term knee injury, which caused her to pull out of upcoming Miami and Rome events.

===Williams vs. Azarenka===
Williams leads the series 18–5. The rivalry began at the 2008 Australian Open, and their most recent match was in the semifinals of the 2020 US Open. Williams holds a 10–1 record in Grand Slams. Azarenka is the only player to win four WTA tour-level finals against Williams, and, despite only winning five matches against Williams, is considered one of the few modern players to truly challenge Williams.<ref>{{cite web|title=Rivalry record: Serena Williams vs Victoria Azarenka|url=http://www.wtatennis.com/photos/1820020/rivalry-record-serena-williams-vs-victoria-azarenka|access-date=October 18, 2020|website=Women's Tennis Association}}</ref>

Williams next lost to Sharapova in the finals of the [[2004 WTA Tour Championships – Singles|2004 WTA Tour Championships]]. Since then, however, Williams has dominated the rivalry, winning all of their clashes, with only three of their matches going to three sets. They met 10 times in Grand Slam tournaments, where Williams leads 9–1. They faced off in a further nine finals, with Williams leading 7–2.
