The1876Boston Red Caps season was the sixth season of the franchise. With the dissolution of theNational Association, the Boston team joined the brand newNational League. The team name was changed from the Boston Red Stockings to theBoston Red Caps to avoid confusion with the newCincinnati Red Stockings team. Some of the players from theprevious year's team defected to other ballclubs, so the team finished further down in the standings this season.
