Allegheny West is a historic neighborhood in Pittsburgh, Pennsylvania's North Side.

[5][6][page needed] The area was frequented by Native Americans until late in the 18th century.

In 1787 David Redick began a survey of the area, with land to be given to Continental soldiers as part of their pay for service in the American Revolution.

Houses were first built in the district in 1846-47 and streets were laid out about the same time.

[1] In the late 19th century Ridge Avenue became known as "Millionaire's Row" with mansions built for Henry W. Oliver, William Penn Snyder, Harmar Denny, Alexander M. Byers, and others.
