Shady Grove is a former townsite and unincorporated community in Buchanan County, Iowa, United States, between the cities of Brandon and Jesup.

Shady Grove was founded in 1857 at the western edge of Jefferson Township, near the Buchanan-Black Hawk county line.

Despite attracting businesses including a machinery dealership, a creamery, a church and a general store, the town was never incorporated.

The town remained on county maps as late as the 1990s, though there was nothing left to mark the community other than a giant machine shed with the words "Shady Grove" on it.

The tombstones have tumbled and been broken up and some possibly lost due to flooded creeks and cattle tromps.
