The Congress Lands West of Miami River was a land tract in southwest Ohio that was established by the Congress late in the 18th century. It is located south of the Greenville Treaty Line, east of Indiana, and north of the Great Miami River. The original survey in 1798 contained a triangular shaped slice of land, now located in Indiana, that extended to the Greenville line as it ran from Fort Recovery to opposite the mouth of the Kentucky River.
