The Lincoln Log Cabin State Historic Site is an 86-acre (0.3 kmē) history park located eight miles (13 km) south of Charleston, Illinois, near the town of Lerna. Its centerpiece is a replica of the log cabin built and occupied by Thomas Lincoln, father of U.S. President Abraham Lincoln. The younger Lincoln never lived here and visited infrequently, but he provided financial help to the household and, after Thomas died in 1851, Abraham owned and maintained the farm for his stepmother, Sarah Bush Lincoln. Sarah Bush Lincoln lived in the Goosenest Prairie cabin until her death in 1869. The farmstead is operated by the Illinois Historic Preservation Agency.

In 1893, the original Thomas Lincoln log cabin was disassembled and shipped northward to serve as an exhibit at the World's Columbian Exposition in Chicago, Illinois. The original cabin was lost after the Exposition, and may have been used as firewood. However, the cabin had been photographed many times, and an exact replica was built from the photographs and from contemporary descriptions.
