Ormiston Mansion is a 2+1⁄2-story, red brick, late Georgian period house located in east Fairmount Park, Philadelphia.

Many of the original interior features remain including fireplaces with marble mantles and a Scottish bake oven.

The cedar shake roof includes a widow's walk and Federal-style dormers, while six large shuttered windows are on each side of the house, and five on the front.

[4] Edward Burd, a Pennsylvania Supreme Court prothonotary, built the mansion on a plot of 45 acres (18 ha) above the eastern bank of the Schuylkill River.

The city of Philadelphia purchased the mansion and land from Burd's heirs in 1869 to expand Fairmount Park.
