The 1877 major league baseball season was contested from April 30 through October 6, 1877, and saw the Boston Red Caps as the pennant winner of the second season of the National League. There was no postseason.
Over the off-season, in December 1876, two teams were formally kicked out of the league for failing to fulfill their schedules: New York Mutuals and Philadelphia Athletics, contracting the league from eight to six teams.
The Hartford Dark Blue would relocate from Hartford, Connecticut to Brooklyn, New York, as the Brooklyn Hartfords.
