Settled in 1823, Bradford was chartered as a city in 1837 and emerged as a wild oil boomtown in the Pennsylvania oil rush in the late 19th century. The area's Pennsylvania Grade crude oil has superior qualities and is free of asphaltic constituents, contains only trace amounts of sulfur and nitrogen, and has excellent characteristics for refining into lubricants. The Bradford & Foster Brook Railway was built in 1876 as one of, if not the first, monorails in America, when Bradford was a booming oil town. World famous Kendall racing oils were produced in Bradford. Bradford was the site of an important step in the development of personal aviation. In the 1930s, the Taylor Brothers Aircraft Corporation produced an airplane called the Taylor Cub in Bradford. After a fire at the factory, the company was bought by William T. Piper.

The population peaked at 19,306 in 1930, but at the 2010 census had dropped to 8,770.

Bradford is located on U. S. Route 219, just south of its junction with Interstate 86 north of the New York border. According to the U. S. Census Bureau, the city has a total area of 3.5 square miles (9 km2), all land. Bradford is situated in a valley in the Allegheny Mountains and is surrounded by woods and steep hills. Two branches of the Tunungwant Creek enter the city, merge and flow north into the Allegheny River just across the New York border. Bradford Regional Airport is located approximately 15 mile (24 km) south of the city, at Mount Alton. The elevation of the city is 1,443 feet (440 m) above sea level, but the airport is at an elevation of 2,142 feet (653 m) above sea level. Because of the higher elevation, the airport often has the coldest reported air temperatures in Pennsylvania. The airport has one of the few National Weather Service stations across the entire northern tier of the state. Temperatures in the city are typically three to seven degrees warmer than at the airport due to the difference in elevation, and actual city temperatures are more representative of other communities in northern Pennsylvania and southwestern New York than are the airport's.

Late fall/early winter is especially snowy due to heavy amounts of lake effect snow from Lake Erie and, to a lesser extent, Lake Ontario. Lake effect snow during cold snaps in early spring also helps to raise snowfall totals.
