Renovo is a borough in Clinton County, Pennsylvania, northwest of Lock Haven. In 1900, 4,082 people lived there, and in 1910, 4,621 lived there, but in the 2000 census, the borough population was 1,318 and held steady for the 2010 census at 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 West Branch Susquehanna River. The town is the home of the "Flaming Foliage Festival" held each October, generally in 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 venders from the surrounding areas sell food, clothing, and an array of novelties, memorabilia, and souvenirs.
The economy of Renovo and the surrounding area had been 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.
