A sportsperson (American English: Sports person), (gendered as sportsman or sportswoman) or athlete is a person trained to compete in a sport involving physical strength, speed or endurance. Sportspeople may be professional or amateur.

Most professional sportspeople have particularly well-developed physiques obtained by extensive physical training and strict exercise accompanied by a strict dietary regimen.

The word "athlete" is a romanization of the Greek: άθλητὴς, athlētēs, one who participates in a contest; from ἂθλος, áthlos, or ἂθλον, áthlon, a contest or feat. The term may be used as a synonym for sportspeople in general, but it also has stronger connotations of people who compete in athletic sports, as opposed to other sporting types such as horse riding and driving. In British English (as well as other variants in the Commonwealth) athlete can also have a more specific meaning of people who compete in the sport of athletics.

An "all-around athlete" is a person who competes in multiple sports at a high level, for instance, someone who plays both basketball and baseball professionally. Examples of people who played numerous sports professionally are Jim Thorpe, Lionel Conacher, Deion Sanders (male), Danny Ainge (male) and Babe Zaharias (female). Others include Ricky Williams, Bo Jackson, and Damon Allen, each of whom was drafted both by Major League Baseball and by professional gridiron football leagues such as the NFL and the CFL. Another example is Kazushi Sakuraba, a Japanese athlete who competed in both professional wrestling and mixed martial arts and succeeded in both sports. Many Japanese martial artists compete in both wrestling and MMA due to their strong promotions and similarities.

Serena Jameka Williams (born September 26, 1981) is an American professional tennis player and a former world no. 1. The Women's Tennis Association has ranked her world no. 1 in singles on five separate occasions. She became the world no. 1 for the first time on July 8, 2002 and regained this ranking for the fifth time on November 2, 2009. She is the only female player to have won over $35 million in prize money.

Her 27 Grand Slam titles places her ninth on the all-time list: 13 in singles, 12 in women's doubles, and 2 in mixed doubles. She is the most recent player, male or female, to have held all four Grand Slam singles titles simultaneously and only the fifth woman in history to do so. She was also the first woman, along with sister Venus Williams, to hold all four Grand Slam doubles titles simultaneously since Martina Hingis did so in 1998. Her 13 Grand Slam singles titles is sixth on the all-time list. Williams ranks fourth in Grand Slam women's singles titles won during the open era, behind Steffi Graf (22 titles) and Chris Evert and Martina Navratilova (18 titles each). She has won more Major titles in singles, doubles, and mixed doubles than any other active player, male or female.
