Union Star Cemetery lies in the east of Sioux County near Horn, in Section 5 of Township 32 north, Range 53 west. It is listed under Glen, the nearest place in the county, about twelve miles to the south.

Around 49 memorials have been recorded, which is a record of what has been photographed and indexed rather than a count of everyone buried there.

For burial records or plot inquiries, contact the Sioux County Clerk in Harrison. Ownership can also be confirmed through the Nebraska Statewide Cemetery Registry at the State Historical Society.
