Quebec Run Wild Area is a 7,441-acre protected section of Forbes State Forest in southwestern Pennsylvania, notable as the largest roadless wild area in that part of the state. Once an old-growth forest observed as rugged wilderness near the Mason-Dixon survey in 1767, it was heavily logged into the 20th century, with traces of that era still visible. Today it is a healthy third-growth Appalachian forest of rocky streams, diverse wildlife, and more than 23 miles of interconnected trails. Managed as a wild area since 1972 and officially designated in 2004, it is kept largely undeveloped for low-impact recreation.
