The Atlas of Historical County Boundaries Project (AHCBP), is a reference work which aims to provide information and map every county boundary configuration in United States, from the earliest county creation in the 1600s to the present. Every county and county-equivalent entity is mapped at its creation and at all subsequent boundary changes, a process which provides a complete picture of county evolution through time, and leaves no gaps in time or space.

The project is based at the William M. Scholl Center for Family and Community History at the Newberry Library in Chicago, and is funded by the National Endowment for the Humanities (NEH) and the Newberry Library.
