DuBois is a city and the most populous community in Clearfield County, Pennsylvania, United States. DuBois is located approximately 100 miles (160 km) northeast of Pittsburgh. The population was 7,510 as of the 2020 census. It is the principal city in the DuBois, PA Micropolitan Statistical Area. DuBois is also one of two principal cities, the other being State College, that make up the larger State College-DuBois, PA Combined Statistical Area.

Settled in 1812 and platted in 1872, DuBois was incorporated as a borough in 1881 and as a city in 1914.

The town was founded by John Rumbarger, for whom the town was originally named. The Rumbarger Cemetery is all that survives of John Rumbarger's "original settlement" in the city of DuBois. The town was later renamed for local lumber magnate John DuBois, who came from a longstanding American family of French Huguenot descent. Many of the town's original buildings and homes were funded and or donated by Mr. DuBois's lumber mill. In 1938, his nephew, John E. DuBois, donated the family mansion and estate as a permanent home for the DuBois Campus of Penn State University. While DuBois was founded as a lumber town, the mining of bituminous coal quickly became the chief industry in DuBois.

Over the years there have been numerous unsuccessful attempts in 1989, 1995, and 2002 to combine the city with the surrounding Sandy Township, but in 2021 voters in both municipalities successfully voted to consolidate into a new third class city, anticipated to take effect between 2024 and 2026. Combined, the population of DuBois and Sandy Township is approximately 18,000 people.

The Commercial Hotel, since demolished, was listed on the National Register of Historic Places in 1985, and the DuBois Historic District was listed in 1997.

There seems to be some debate as to exactly when Frank Hahne came to DuBois and broke ground on his own facility. One source claims 1898, another 1897. It seems most likely that this occurred between April and the end of 1896. It was on April 16, 1896, that the DuBois Weekly Courier reported: "Some new developments in connection with the brewery may be looked for in the near future."

There were a number of reasons Hahne chose the DuBois site for his facility, but the most frequently cited was the excellence of the water supply. He purchased 2,300 acres (9.3 km) surrounding the local reservoir to protect the watershed from pollution.

By 1906, the brewery had four products on the market: DuBois Wurzburger, Hahne's Export Pilsener, DuBois Porter, and DuBois Budweiser. The Budweiser name would be at the center of controversy for 60 years between DuBois Brewing and Anheuser-Busch.

The DuBois brands soon traveled far and wide for a brewery of its size, ranging up to 150 miles (240 km) away and selling well in Buffalo, Erie and Pittsburgh. The brewery's 300-barrel kettle was kept busy churning out brands, while the left-over grain materials were pressed and sold for cattle feed and grist mills in the rural areas surrounding DuBois.

As with many other American breweries, DuBois Brewing moved right along until 1918 and the advent of Prohibition. The brewery shifted production to "near beer" and soft drinks and opened the H&G Ice Company. According to the April 7, 1933, DuBois Courier, the brewery won the honor of being one of only two breweries in the entire nation that had never violated or been suspected of violating the Prohibition laws since the 18th Amendment went into effect. As a result, DuBois Brewing Company was issued license number G-2, allowing them to resume brewing immediately upon the enaction of the 21st Amendment.

Frank Hahne died in 1932, and the brewery was passed to his only son, Frank Hahne Jr., whose own only son died in infancy, leaving the family without an heir. Hahne Jr. sold the brewery to Pittsburgh Brewing in 1967.

The brewery was torn down in late 2003.
