Meridian-Baseline State Park is a state park in the U.S. state of Michigan in both Ingham County and Jackson County. This 88-acre (36 ha) landlocked area contains the intersection of the Michigan meridian and the baseline used for the Michigan Survey. The park is marked with two monuments that show where the two mismatched baselines meet the principal meridian at the North Initial Point and South Initial Point. The park is not accessible to the public, and can only be reached by a 20-minute drive across private property. It is currently being preserved for its historic value.
