LeBron Raymone James Sr. (born December 30, 1984) is an American professional basketball player for the Los Angeles Lakers of the National Basketball Association (NBA). Nicknamed "King James", he is widely recognized as one of the greatest players in the sport's history and is often compared with Michael Jordan in debates over the greatest basketball player of all time.[dubious – discuss][a] James has won four NBA championships from 10 NBA Finals appearances, having made eight consecutive appearances between 2011 and 2018. He also won the inaugural NBA Cup in 2023 with the Lakers and three Olympic gold medals as a member of the U.S. national team.

In addition to being the NBA's all-time leading scorer and ranking fourth in career assists, James holds several individual honors: four Most Valuable Player (MVP) Awards, four Finals MVP Awards, three All-Star Game MVP Awards, and the inaugural NBA Cup MVP award. He has been named an All-Star a record 20 times, selected to the All-NBA Team 20 times (including 13 First Team selections) and the All-Defensive Team six times, and was a runner-up for the NBA Defensive Player of the Year Award twice in his career. James is noted for his longevity and is currently the oldest player in the NBA.

James grew up playing basketball for St. Vincent–St. Mary High School in his hometown of Akron, Ohio. He was heavily touted by the national media as a future NBA superstar for his all-around scoring, passing, athleticism and playmaking abilities. A prep-to-pro, James was selected by the Cleveland Cavaliers with the first overall pick of the 2003 NBA draft. Named the 2004 NBA Rookie of the Year, he soon established himself as one of the league's premier players, leading the Cavaliers to their first NBA Finals appearance in 2007 and winning the NBA MVP award in 2009 and 2010. James left in 2010 as a free agent to join the Miami Heat; this was announced in a nationally televised special titled The Decision and is among the most controversial free agency moves in sports history, despite the show raising millions for national charities.

James won his first two NBA championships while playing for the Heat in 2012 and 2013; in both of these years, he also earned the league's MVP and Finals MVP awards. After his fourth season with the Heat in 2014, James opted out of his contract and returned to the Cavaliers. In 2016, he led the Cavaliers to victory over the Golden State Warriors in the Finals by coming back from a 3–1 deficit, delivering the team's first championship and ending the Cleveland sports curse. In 2018, James exercised his contract option to leave the Cavaliers and signed with the Lakers, where he won the 2020 NBA championship and his fourth Finals MVP. On February 7, 2023, James surpassed Kareem Abdul-Jabbar to become the leading scorer in league history.

Off the court, James has earned further wealth and fame from numerous endorsement contracts. He is the first player in NBA history to accumulate $1 billion in earnings as an active player. James has been featured in books, documentaries (including winning three Sports Emmy Awards as an executive producer), and television commercials. He was among Time's 100 most influential people in the world in 2005, 2013, 2017, and 2019 – the most selections for a professional athlete. James has won 20 ESPY Awards, hosted Saturday Night Live, and starred in the sports film Space Jam: A New Legacy (2021). He has been a part-owner of Liverpool F.C. since 2011 and leads the LeBron James Family Foundation, which has opened an elementary school, housing complex, retail plaza, and medical center in Akron.
