Pittsburgh Brewing Company is a beer company headquartered in the Lawrenceville neighborhood of Pittsburgh, Pennsylvania, United States, best known for producing brands such as Iron City Beer, I.C. Light Beer, I.C. Light Mango, Old German, and Block House Brewing. Until August 2009, all production was conducted at its Lawrenceville facility. From August 2009 to 2021, their products were contract brewed at City Brewing Company in the facility once produced Rolling Rock. On February 4, 2021, Iron City Beer's Instagram account announced that Pittsburgh Brewing Company would resume production of its own product in a new production brewery in Creighton, Pennsylvania, in the original Pittsburgh Plate Glass Company plant. At its opening, the facility is capable of producing 150,000 BBLs of beer annually.

Rolling Rock is a 4.4% abv American lager launched in 1939 by the Latrobe Brewing Company. Although founded as a local beer in Western Pennsylvania, it was marketed aggressively and eventually became a national product. The brand was sold to Anheuser-Busch of St. Louis, Missouri, in mid-2006, which transferred brewing operations to New Jersey while continuing to label the new beer prominently with the name of Latrobe.
