Allen Steam Station
- Capacity: 1,140 megawatts
- Location: Gaston County, North Carolina
- Commercial Date: 1957

Located in Gaston County, North Carolina, Allen Steam Station is a five-unit coal-fired generating facility. Units 1 and 2 began operating in 1957; unit 3 in 1959; unit 4 in 1960 and unit 5 in 1961. Named for George Garland Allen, a former president and first chairman of the board for Duke Power, the Allen facility is the only Duke Energy station with five units under one roof.
In 2006, Duke Energy began installing flue gas desulfurization equipment—commonly known as scrubbers. This equipment will reduce the station’s sulfur dioxide emissions by approximately 95 percent. The project is expected to be completed in 2009.
