Bradford County is a county in the Commonwealth of Pennsylvania. As of the 2020 census, its population was 59,967. Its county seat is Towanda. The county was created on February 21, 1810, from parts of Lycoming and Luzerne Counties. Originally called Ontario County, it was reorganized and separated from Lycoming County on October 13, 1812, and renamed Bradford County for William Bradford, who had been a chief justice of the Pennsylvania Supreme Court and United States Attorney General. The county is part of the Northeast Pennsylvania region of the state.

Bradford County comprises the Sayre, Pennsylvania micropolitan statistical area.

The county is not to be confused with the city of Bradford, which is in McKean County, 141 miles to the west via U.S. Route 6.

As noted above, Bradford County was originally named Ontario County. The county was reorganized and renamed in 1812, but a section of north Philadelphia in which major east–west streets are named after Pennsylvania counties retains an Ontario Street, between Westmoreland and Tioga Streets. Two short Bradford Streets are in northeast Philadelphia, about 4 miles from Ontario Street.

Bradford County is the ancestral home of the Tehotitachsae indigenous people of North America. Their principal village, Gohontoto, was on the site of the present Borough of Wyalusing.

According to the U.S. Census Bureau, the county has a total area of 1,161 square miles (3,010 km), of which 1,147 square miles (2,970 km) are land and 14 square miles (36 km) (1.2%) are covered by water. It is the second-largest county in Pennsylvania by land area and third-largest by total area.

Bradford has a warm-summer humid continental climate (Dfb) and average monthly temperatures in Towanda range from 24.5 °F in January to 70.6 °F in July.
