The Protestant Episcopal Cathedral Foundation was chartered by Congress on January 6, 1893. This Episcopal Church organization oversees Washington National Cathedral (formally known as the Cathedral Church of Saint Peter and Saint Paul) and its sister institutions.

The bishop of the Episcopal Diocese of Washington serves as the Foundation's chair and president, while the dean of Washington National Cathedral serves as the vice chair of the Foundation's board of trustees.

The Foundation comprises four institutions: Washington National Cathedral (established 1893), the National Cathedral School for girls (established 1900); St. Albans School for boys (established 1909), and Beauvoir, The National Cathedral Elementary School (established 1933). All of the schools are located on the 57-acre grounds of the Cathedral. The College of Preachers was formerly housed at a stone Gothic Revival building adjacent to the cathedral. It operates as a continuing education center for Episcopal clergy. After the 2011 Virginia earthquake, the Foundation raised money for the costly repairs required to fix damage.
