Sons of Union Veterans of the Civil War (SUVCW) is an American fraternal organization, the legal successor to the Grand Army of the Republic (GAR). Founded in late 1881, it was originally one of several competing organizations of descendants of Union veterans. By 1886, others had joined the SUVCW. Local camps decorate veterans' graves on Memorial Day and have activities to preserve history and commemorate military service. For example, members of Alden Skinner Camp 45 organized and now maintain the New England Civil War Museum.
