The Portland Duffs were a minor league baseball team based in Portland, Maine. From 1913 to 1915, the Portland "Duffs" played as members of the Class B level New England League, winning the 1915 league championship.

The Duffs were named after their owner/manager, Baseball Hall of Fame member Hugh Duffy. After the New England league folded following the 1915 season, the Duffs played the 1916 and 1917 seasons in the Eastern League. Portland returned to New England League membership for the 1919 and 1926 to 1930 seasons, with Boston Red Sox Hall of Fame member Duffy Lewis managing the team for three seasons.

The Portland teams hosted home New England League and Eastern League minor league games at Bayside Park. The ballpark was built for the 1913 season after Hugh Duffy founded the New England League team.

The Portland Duffs teams were preceded in minor league play by 1908 Portland Blue Sox who played in the final season of the Maine State League.
