The 2000 World Series was the championship series of Major League Baseball's (MLB) 2000 season. The 96th edition of the World Series, it was a best-of-seven playoff between crosstown opponents, the two-time defending World Series champions and American League (AL) champion New York Yankees and the National League (NL) champion New York Mets. The Yankees defeated the Mets, four games to one, to win their third consecutive championship and 26th overall. The series was often referred to as the "Subway Series", referring to the longstanding matchup between New York baseball teams; it was the first World Series contested between two New York teams since the 1956 World Series and the first since the New York Giants and the Brooklyn Dodgers moved west to California in 1958 and the subsequent formation of the Mets in 1962. This World Series that featured teams from the same city or state, was the first of its kind since 1989 between the Oakland Athletics and the San Francisco Giants. Yankees shortstop Derek Jeter was named the World Series Most Valuable Player.

The 2000 Major League Baseball season ended with the New York Yankees defeating the New York Mets in five games, for their third consecutive World Series title. The 2000 World Series was known as the Subway Series because both fans and the two teams could take the subway to and from every game of the series.
