Carrie Furnace is a retired blast furnace located along the Monongahela River in the Pittsburgh area industrial town of Swissvale, Pennsylvania. It was one of the structures comprising the Homestead Steel Works. The Carrie Furnaces were built in 1884 and they operated until 1982. During its peak, the site produced 1,000 to 1,250 tons of iron per day. All that is left of the site are furnaces #6 and #7, which operated from 1907 to 1978, and its hot metal bridge (not to be confused with the Hot Metal Bridge farther downstream). The furnaces, designated a National Historic Landmark in 2006, are among the only pre-World War II 20th century blast furnaces to survive.

The site is currently managed by the nonprofit Rivers of Steel Heritage Corporation, which conducts tours and other programs from May through October.
