The Springfield–Charlestown Hyphens were a minor league baseball team representing the partner cities of Springfield, Vermont and Charlestown, New Hampshire.
The Springfield–Charlestown Hyphens were formed in 1911, as the result of a business venture in nearby Brattleboro, Vermont and the strength of the partnership between Springfield and Charlestown.
Because Vermont's Blue Laws in the era did not allow businesses to be open on Sundays, the official New Hampshire location of the island provided an escape from the legal issue on weekends.
Springfield–Charlestown joined the Brattleboro Islanders, Bellows Falls Sulphites and Keene Champs in forming the new league.
