Which MLB team has won the most World Series titles?

The New York Yankees have won the most World Series titles, with 27 championships. Their total is the highest in Major League Baseball, ahead of the St. Louis Cardinals with 11.

The Yankees’ dominance began with their first championship in 1923, the inaugural season of the original Yankee Stadium. They became especially formidable from the 1930s onward, winning titles behind stars such as Babe Ruth, Lou Gehrig, Joe DiMaggio, Mickey Mantle and Yogi Berra. The club also won five consecutive World Series from 1949 through 1953, still the longest championship streak in MLB history.

New York’s 27 titles came in 41 World Series appearances. The most recent championship was in 2009, when the Yankees defeated the Philadelphia Phillies in six games. Their 27 victories are a franchise total, including the seasons when the team was known as the New York Highlanders before adopting the Yankees name in 1913.

A common mix-up is confusing World Series victories with American League pennants. The Yankees hold the record for both, but the World Series count measures championships won against the league’s postseason opponent.
