Allegheny Commons is a municipal park located in Pittsburgh's North Side.

[2][Note 1] The park was once free grazing land which surrounded the first 32 blocks of Allegheny City in John Redick's 1784 town plan.

[3] It was re-made into a municipal park in the 1860s by landscape architects hired by Allegheny City.

A non-profit organization, The Allegheny Commons Initiative maintains the park acting as a liaison[5] between it and the city through advocacy, fundraising, and project management.

The site is famous for housing 118 Confederate soldiers after their capture in Morgan's Raid a dozen miles to the west.
