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.
Led by starting pitchers Johnny Sain and Warren Spahn (who combined for 39 victories), and the hitting of Bob Elliott, Jeff Heath, Tommy Holmes and rookie Alvin Dark, the 1948 Braves captured 91 games to finish 61⁄2 paces ahead of the second-place St. Louis Cardinals. They also attracted 1,455,439 fans to Braves Field, the third-largest gate in the National League and a high-water mark for the team's stay in Boston.
