The New York Yankees are an American professional baseball team based in the New York City borough of the Bronx. The Yankees compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. They are one of two major league clubs based in New York City, the other is the National League (NL)'s New York Mets. The team was founded in 1903 when Frank Farrell and Bill Devery purchased the franchise rights to the defunct Baltimore Orioles (no relation to the current team of the same name) after it ceased operations and used them to establish the New York Highlanders. The Highlanders were officially renamed the New York Yankees in 1913.

The team is owned by Yankee Global Enterprises, a limited liability company that is controlled by the family of the late George Steinbrenner. Steinbrenner purchased the team from CBS in 1973. Brian Cashman is the team's general manager, and Aaron Boone is the team's field manager. The team's home games were played at the original Yankee Stadium in the Bronx from 1923 to 1973 and from 1976 to 2008. In 1974 and 1975, the Yankees shared Shea Stadium with the Mets, in addition to the New York Jets and the New York Giants. In 2009, they moved into a new ballpark of the same name that was constructed adjacent to the previous facility, which was closed and demolished. The team is perennially among the leaders in MLB attendance.

Arguably one of the most successful professional sports team in the United States, the Yankees have won 19 American League East Division titles, 40 American League pennants, and 27 World Series championships, all of which are MLB records. The team has won more titles than any other franchise in the four major North American sports leagues, after briefly trailing the NHL's Montreal Canadiens between 1993 and 1999. The Yankees have had 44 players and 11 managers inducted into the National Baseball Hall of Fame, including many of the sport's most iconic figures in history such as Babe Ruth, Lou Gehrig, Joe DiMaggio, Mickey Mantle, Yogi Berra, and Whitey Ford; more recent inductees include Mariano Rivera, and Derek Jeter, who received the two highest vote percentages of all Hall of Fame members. According to Forbes, the Yankees are the second-highest valued sports franchise in the world, after the NFL's Dallas Cowboys, with an estimated value in 2022 of approximately $6 billion. The team has garnered enormous popularity and a dedicated fanbase, as well as widespread enmity from fans of other MLB teams. The team's rivalry with the Boston Red Sox is one of the most well-known rivalries in North American sports. The team's logo is internationally known as a fashion item, and as an icon of New York City and the United States.

From 1903 through the 2022 season, the Yankees' overall win–loss record is 10,602-8,000 (a .570 winning percentage).
