The Union School is an historic, American building that is located at 516-518 Bethlehem Pike in the Fort Washington section of Whitemarsh Township, Pennsylvania.

As part of his will, local Quaker businessman Samuel Morris stipulated that a sum of money from his estate be set for the building of a school and a teacher's salary.

The school and attached schoolmaster's house were built using fieldstone portions that were covered in painted stucco.

The trust fund established by Samuel Morris remains in existence today, supporting education in the townships of Whitpain, Whitemarsh and Upper Dublin in Pennsylvania.

The museum of the Fort Washington Historical Society in the Clifton House contains a replica of the school room.
