Embreeville is a historical unincorporated community, little more than a rural stretch of road with a few businesses and homes, in Newlin Township, Pennsylvania, United States, on a bend of Brandywine Creek.

It is approximately 30 miles (48 km) west of Philadelphia, and north of Unionville.

[1] During the 19th and 20th centuries Embreeville was best known as the site of the county poor house and the Chester County Asylum for the Insane, renamed Embreeville State Hospital in 1938 and closed in 1980.

The Star Gazers' Stone marked an important astronomical observation point used by Charles Mason and Jeremiah Dixon in 1764 in surveying the Mason-Dixon line, which lies 15 miles south of the stone.

It is also the location to a Pennsylvania state police station.
