Lincoln State Park is a state park of Indiana, United States. It is located in southern Indiana in Spencer County approximately 35 miles (56 km) east of Evansville. The park was established in 1932 and encompasses 1,747 acres (707 ha). There are 10 miles (16 km) of trails in the park. Many of the recreational facilities found within the park were constructed by the Civilian Conservation Corps during the Great Depression.
The park was originally established as a memorial to Abraham Lincoln's mother Nancy Hanks Lincoln, whose gravesite is now contained within the adjacent Lincoln Boyhood National Memorial. The family of Abraham Lincoln lived in Spencer County for 14 years, from 1816 to 1830. Lincoln State Park contains numerous sites significant to this period.
