Duquesne (/djuːˈkeɪn/ dew-KAYN) is a city along the Monongahela River in Allegheny County, Pennsylvania, United States, within the Pittsburgh metropolitan area.

The city's population peaked in 1930, then declined with the Great Depression and deindustrialization beginning after World War II.

Today a stark post-industrial landscape, Duquesne has fewer total residents (5,565 at the 2010 U.S. census) than were the city's mill workers in 1948.

[citation needed] Duquesne was designated a financially distressed municipality in 1991 by the state.

Duquesne is located along the Monongahela River, approximately 12 miles (19 km) south of Pittsburgh.

Since July 2007, the Allegheny Intermediate Unit (AIU) has managed all academic and business operations of the Duquesne's K–8 school district.
