Reeve Township is one of ten townships in Daviess County, Indiana. As of the 2020 census, its population was 624 (down from 631 at 2010[3]) and it contained 246 housing units.[4]
Reeve Township was organized on May 12, 1817, at the first meeting of the Daviess County Commissioners. It was named for its earliest resident, South Carolina native Joshua Reeve, who had settled in the township in 1808. As the first settler in the area, Reeve lived in an isolated cabin in the forest; in order to obtain needed supplies, he was forced to travel to Vincennes. Desiring to simplify his travels, Reeve blazed a trail through the woods from his home to Vincennes; in later years, the route became a road, and by the early twentieth century it had become one of the county's leading highways.[5]
According to the 2010 census, the township has a total area of, of which (or 97.62%) is land and (or 2.36%) is water.[3] Big Piney Pond and Little Piney Pond are in this township.
The township contains three cemeteries: the Alfordsville Christian Cemetery just north of town, Old Union Cemetery on the land originally owned by James Allen and his wife, Mary Hizer Allen, southwest of town, and the Helpenstine Cemetery (also known as the McCord Cemetery) east of town on the County Line Road.
