Phil-Ellena was the stately home of George Washington Carpenter in Germantown, Pennsylvania, now the West Mount Airy neighborhood of Philadelphia.

He subdivided some of the property, but on a 300-acre parcel[1] near what is now the intersection of Germantown Avenue and Pelham Road he constructed his country estate known as Phil-Ellena.

Named for his second wife, Ellen, the Greek Revival house was "one of the most noted homes in the country.

"[2][3] Carpenter, a noted scientist, built a Greek temple on the estate to house his collections of specimens.

[5] Visitors to Phil-Ellena included Thomas Nuttall and John James Audubon.
