The 1951 World Series matched the two-time defending champion New York Yankees against the New York Giants, who had won the National League pennant in a thrilling three-game playoff with the Brooklyn Dodgers on the legendary home run by Bobby Thomson (the Shot Heard 'Round the World).

In the Series, the Yankees showed some power of their own, including Gil McDougald's grand slam home run in Game 5, at the Polo Grounds. The Yankees won the Series in six games, for their third straight title and 14th overall. This would be the last World Series for Joe DiMaggio, who retired afterward, and the first for rookies Willie Mays and Mickey Mantle.

This was the last Subway Series the Giants played in. Both teams would meet again eleven years later after the Giants relocated to San Francisco. They have not played a World Series against each other since. This was the first World Series announced by Bob Sheppard, who was in his first year as Yankee Stadium's public address announcer. It was also the first World Series to be televised exclusively by one network (NBC) as well as the first to be televised nationwide, as coaxial cable had recently linked both coasts.
