Park Hills is a city in St. Francois County, Missouri, United States.

The formerly incorporated village of Fairview Acres had previously merged with Flat River on November 8, 1983.

The name Park Hills was submitted by Mildred Lee, a lifelong resident and a former teacher of Flat River.

The inspiration came from its hilly terrain in the foothills of the Ozark Mountains and the many parks that surround the area.

It is adjacent to St. Joe State Park, and nearby the state parks of St. Francois, Hawn, Elephant Rocks, Johnson's Shut-Ins, Taum Sauk Mountain, and Washington.

The Eugene Field School was added to the National Register of Historic Places in 2005.
