The community of Roscommon was first settled as early as 1845 by George Robinson of Detroit shortly after Roscommon County was organized in 1840. The community was named after the county, which itself was named after County Roscommon in Ireland. The Roscommon post office was established on January 9, 1873, with Alfred Bennett serving as the first postmaster. In 1875, Roscommon became the county seat and incorporated as a village in 1882.
Beginning in 1979, the annual Michigan's Firemen's Memorial Festival is held in Roscommon and commemorates firefighters who died while protecting their communities.
