The 2014 World Series was the championship series of Major League Baseball's (MLB) 2014 season. The 110th edition of the World Series, it was a best-of-seven playoff between the National League (NL) champion San Francisco Giants and the American League (AL) champion Kansas City Royals. The series was played from October 21 to 29. The Giants defeated the Royals four games to three to clinch their third World Series championship in a five-season span (2010–14), and their third overall since the club's move to San Francisco from New York. It was the Giants' eighth World Series championship in franchise history, and the Giants became the first team in MLB history to win the World Series as a number five seed. The series was also the sixth straight World Series to be won by a team that had missed the playoffs the year before.

The World Series is the annual final championship series of Major League Baseball (MLB) in the United States and Canada. It has traditionally been held in October, though some more recent editions were contested in November due to expanded playoffs and/or season delays. It has been contested since 1903 between the champion teams of the American League (AL) and the National League (NL). The winner of the World Series championship is determined through a best-of-seven playoff, and the winning team is awarded the Commissioner's Trophy.
