Foxburg is a borough in Clarion County, Pennsylvania, United States.

Samuel Mickle Fox (1763–1808), along with his brother George and brothers-in-law Joseph Parker Norris and George Roberts, purchased a number of tracts of land in western Pennsylvania from the Commonwealth during the 1790s.

Six of these tracts, numbered #5725–5730, comprising 6,600 acres (2,700 ha), were contiguous and located along the Allegheny north of its confluence with Toby's Creek (today's Clarion River).

Samuel's son Joseph purchased these tracts from his father's estate in 1816 and established a residence here ten years later.

The town of Foxburg was founded amidst the oil developments in western Pennsylvania in 1870.

The town is home to the nine-hole Foxburg Country Club, founded in 1887.

Pennsylvania Route 58 passes through the borough, crossing the Allegheny on the new Foxburg Bridge, which opened in 2009.

About 14.7% of families and 20.8% of the population were below the poverty line, including 39.0% of those under the age of eighteen and 7.0% of those sixty five or over.
