Munhall is a borough in Allegheny County, Pennsylvania, United States, on the west bank of the Monongahela River.

A large part of the Homestead Works of the Carnegie Steel Company existed in Munhall.

[4] The borough was formed on June 24, 1901, out of a part of Mifflin Township,[5] and named for John Munhall, the original owner of the town site.

Across the Monongahela River, Munhall runs adjacent with (from north to southeast) the Pittsburgh neighborhood of Swisshelm Park, Swissvale and Rankin.

This large "LifeStyle" shopping center was built on the former site of the Carnegie Steel Works.

The Byzantine Catholic Cathedral of St. John the Baptist, serving the Archeparchy of Pittsburgh, is also located in the borough.

The Great Allegheny Passage, part of a shared-use path connecting Pittsburgh to Washington, D.C., runs through the borough parallel to the river.
