Derek Sanderson Jeter ( JEE-tər; born June 26, 1974) is an American former professional baseball shortstop, businessman, and baseball executive. He has been the chief executive officer (CEO) and part owner of the Miami Marlins of Major League Baseball (MLB) since September 2017. As a player, Jeter spent his entire 20-year 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 (99.75%), the second-highest percentage in MLB history (behind only Mariano Rivera) and the highest by a position player.

A five-time World Series champion, Jeter is regarded as one of the primary contributors to the Yankees' success of 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 Roberto Clemente Award. Jeter was the 28th player to reach 3,000 hits and finished his career ranked sixth in MLB history in career hits 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 was 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.
