10 of the lowest cities and towns in Illinois by elevation
These towns aren't ranked against each other. A published elevation is a single point chosen to represent a town, not a reading of the whole town, and different sources choose different points. Each figure here is one such reading, so we do not say which of these towns sits lowest. They're listed alphabetically below.

Methodology & sources
About this list. Incorporated cities and towns are municipalities recorded by the U.S. Census Bureau; census-designated places, townships, and unincorporated communities are not included. Elevation figures come from the U.S. Geological Survey's 3D Elevation Program. Each elevation is approximate. A town does not have one single elevation — different sources choose different points to represent it, so the figure depends on which point is measured, and ours can differ from the figure other sources publish. The elevation column in our downloadable City lists gives these same figures to one decimal place. Where a candidate town's figures don't hold together well enough to stand behind, it's left out rather than the list padded — so some states run to fewer than ten.
