Renovo is a borough in Clinton County, Pennsylvania, United States, 28 miles (45 km) northwest of Lock Haven. In 1900, 4,082 people lived there, and in 1910, 4,621 lived there, but in the 2010 census the borough population was 1,228.
The borough is located on the West Branch Susquehanna River, and along Pennsylvania's Bucktail State Park Natural Area, centered on Pennsylvania Route 120, which winds through the surrounding mountains following the river. The town is the home of the "Flaming Foliage Festival" held each October, generally on the second weekend, celebrating the fall colors of the trees on the area's many mountains. The festival includes a parade and the crowning of a queen, usually chosen from one of the nearby high schools. The festival serves as a "homecoming" event for former residents of Renovo, many of whom return annually for the event. Various vendors from the surrounding areas sell food, clothing, and an array of novelties, memorabilia, and souvenirs.
The economy of Renovo and the surrounding area were primarily based on lumbering, until the first-growth forest was almost entirely stripped away, and the industry collapsed. There are also deposits of bituminous coal and fire clay in the region.
