Largest Landowners in Illinois

The most prolific landowners in Illinois — ranked by how many parcels each holds across every county this site publishes, acreage breaking ties.

Some counties in Illinois do not publish parcel acreage, so acres sums the county's own figure where there is one and the mapped boundary where there is not — marked † below.

Owners are grouped on the name each county publishes. Collapsing spellings that mean the same owner would merge holdings that really are one, and is worth doing — but a wrong merge attributes land to someone who does not own it, on a page that names them, so until those rules are tested against real deeds the county’s own spelling is what is published here.
