Derek Sanderson Jeter (/ˈdʒiːtər/ JEE-tər; born June 26, 1974), nicknamed "the Captain", is an American former professional baseball player, businessman, and baseball executive. A shortstop, Jeter spent his entire 20-year Major League Baseball (MLB) career with the New York Yankees. He was elected to the Baseball Hall of Fame in his first year of eligibility in 2020; he received 396 of 397 possible votes, the second-highest percentage in MLB history (behind only teammate Mariano Rivera) and the highest by a position player. He was the chief executive officer (CEO) and part owner of the league's Miami Marlins from September 2017 to February 2022.

A five-time World Series champion with the Yankees, Jeter is regarded as a central contributor to the franchise's dynasty during the late 1990s and early 2000s for his hitting, base-running, fielding, and leadership. He is the Yankees' all-time career leader in hits (3,465), doubles (544), games played (2,747), stolen bases (358), times on base (4,716), plate appearances (12,602) and at bats (11,195). His accolades include 14 All-Star selections, five Gold Glove Awards, five Silver Slugger Awards, two Hank Aaron Awards, and a 2009 Roberto Clemente Award. Jeter was the 28th player to reach 3,000 hits and finished his career sixth in MLB history in career hits (3,465), second all-time among right-handed hitters behind Hank Aaron, and first among shortstops. In 2017, the Yankees retired his uniform number 2.

The Yankees drafted Jeter out of high school in 1992, and he debuted in the major leagues at age 20 in 1995. The following year, he became the Yankees' starting shortstop, won the Rookie of the Year Award, and helped the team win the 1996 World Series over the Atlanta Braves. Jeter continued to excel during the team's championship seasons of 1998–2000; he finished third in voting for the American League (AL) Most Valuable Player (MVP) Award in 1998, recorded multiple career-high numbers in 1999, and won both the All-Star Game MVP and World Series MVP Awards in 2000. He consistently placed among the AL leaders in hits and runs scored for most of his career, and served as the Yankees' team captain from 2003 until his retirement in 2014. Throughout his career, Jeter contributed reliably to the Yankees' franchise successes. He holds many postseason records, and has a .321 batting average in the World Series. Jeter has earned the nicknames "Captain Clutch" and "Mr. November" due to his outstanding play in the postseason.

Jeter is one of the most heavily marketed athletes of his generation and is involved in numerous product endorsements. As a celebrity, his personal life and relationships with other celebrities have drawn the attention of the media.

Derek Sanderson Jeter was born on June 26, 1974, in Pequannock Township, New Jersey, the son of accountant Dorothy (née Connors) and substance abuse counselor Sanderson Charles Jeter. His mother is of English, German, and Irish ancestry, while his father is African-American. They met while serving in the United States Army in Germany. His father played baseball at Fisk University in Tennessee as a shortstop, and holds a PhD. When Jeter was a child, his parents made him sign a contract every year that defined acceptable and unacceptable forms of behavior. Dorothy instilled a positive attitude in her son, insisting that he not use the word "can't." It was a baseball family, and Jeter's younger sister Sharlee (born c. 1979) was a softball star in high school.

The Jeters lived in New Jersey until Derek was four, at which point they moved to Kalamazoo, Michigan. At age five, Jeter began playing little league baseball. The children lived with their parents during the school year and spent their summers with their grandparents in West Milford, New Jersey. Attending New York Yankees games with his grandparents, Jeter became a passionate fan of the team. Watching star outfielder Dave Winfield inspired him to pursue a career in baseball.

Jeter attended Kalamazoo Central High School, where he ran cross country in the fall, played basketball in the winter and baseball in the spring. Jeter posted high batting averages for the school's baseball team; he batted .557 in his sophomore year and .508 as a junior. In his senior year, he batted .508 and compiled 23 runs batted in (RBIs), 21 walks, four home runs, a .637 on-base percentage (OBP), a .831 slugging percentage (SLG), 12 stolen bases (in 12 attempts), and only one strikeout.

Jeter received several honors after his senior season, including the Kalamazoo Area B'nai B'rith Award for Scholar Athlete, the 1992 High School Player of the Year Award from the American Baseball Coaches Association, the 1992 Gatorade High School Player of the year award, and USA Today's High School Player of the Year. He also received an All-State honorable mention in basketball. Jeter earned a baseball scholarship to attend the University of Michigan and play college baseball for the Michigan Wolverines. Jeter enrolled at the University of Michigan as an undergraduate student in fall 1992, but left in 1993 after he was drafted by the New York Yankees.
