The 1948 World Series was the championship series in Major League Baseball for the 1948 season. The 45th edition of the World Series, it matched the American League (AL) champion Cleveland Indians and the National League (NL) champion Boston Braves. The Braves had won the National League pennant for the first time since the "Miracle Braves" team of 1914, while the Indians had spoiled a chance for the only all-Boston World Series by winning a one-game playoff against the Boston Red Sox for the American League flag. Though superstar pitcher Bob Feller failed to win either of his two starts, the Indians won the Series in six games to capture their second championship and their first since 1920.

The 1948 Boston Braves season was the 78th consecutive season of the Major League Baseball franchise, its 73rd in the National League. It produced the team's second NL pennant of the 20th century, its first since 1914, and its tenth overall league title dating to 1876.
