The Florida Marlins' 2003 season was the 11th season for the Major League Baseball (MLB) franchise in the National League. The Marlins were the National League Wild Card winners, the National League Champions, and the World Series Champions. They defeated the New York Yankees in the World Series in six games to win their second World Series championship. The Marlins became the second team in baseball history to win a World Series championship despite being 10 or more games below .500 (as low as 19–29) at some point in the season; the other team was the 1914 Boston Braves.
This was the last Marlins team to make the postseason until 2020, and last Marlins team to make the postseason in a full season until 2023.
