Wabash Township is one of ten townships in Gibson County, Indiana, United States. As of the 2020 census, its population was 52 (up from 30 at 2010[3]) and it contained 22 housing units.[4] Wabash Township has no organized seat within the township, as the only settlement is in two river camps Crawleyville and Jimtown. The township seat is Owensville, in Montgomery Township. This area is occasionally referred to as the "Tail of Gibson County", owing to its shape and position within the county. Nevertheless, the township is a panhandle of Gibson County, bordered by the Wabash River to the north, northwest, west, and in some parts, east, even southeast, and by Posey County to the south.
Wabash Township was established in 1838, and named from the Wabash River.[5]
According to the 2010 census, the township has a total area of, of which (or 93.45%) is land and (or 6.55%) is water.[3] Lakes in this township include Foote Pond and Goose Pond.
