Brooklawn is a historic house located on 1825 Newark Road in West Marlborough Township, Chester County, in the U.S. state of Pennsylvania.

A red-brick Federal-style mansion of architectural significance, it was listed on the National Register of Historic Places on January 24, 2022.

[2] Philadelphia-based architect Arthur Ingersoll Meigs designed an extension to the mansion in 1931 (hence its NRHP architectural significance) and added a spring house, servants' quarters, and garage.

[3] Brooklawn was the home of U.S. district court judge John Hannum (1915–2007) and his wife, Nancy Penn Smith Hannum (1919–2010), who served as master of foxhounds for Stewart's Cheshire Hunt for decades and was a prominent Chester County conservationist.
