Monongahela,[4] referred to locally as Mon City, is a third class city in Washington County, Pennsylvania, United States. The population was 4,149 at the 2020 census.[5] It is part of the Pittsburgh metropolitan area, about 17 miles (27 km) south of Pittsburgh proper.

The city of Monongahela sits at a location where several locally important Pennsylvania state routes meet: a concurrency between Pennsylvania routes 88, 136, and 837 makes up most of the length of the city's Main Street, and the city's Park Avenue carries Pennsylvania route 481 to its northern terminus at Main Street.

Monongahela is one of just two cities in Washington County, and is the second smallest city in Pennsylvania (after Parker). The town is served by the Ringgold School District.
