Nicola D'Ascenzo was an Italian-born American stained glass designer, painter and instructor. He is best known for creating stained glass windows for the Washington Memorial Chapel in Valley Forge, Pennsylvania; the Nipper Building in Camden, New Jersey; the Loyola Alumni Chapel of Our Lady at Loyola University Maryland; the Folger Shakespeare Library and Washington National Cathedral, both in Washington, D.C.

Washington Memorial Chapel in Valley Forge National Historical Park is a national memorial dedicated to General George Washington and an active Episcopal parish in Valley Forge, Pennsylvania. The church was inspired by a sermon preached by Anglican minister Reverend Dr. W. Herbert Burk, founder and first rector of the parish. The building was designed by architect Milton B. Medary. It was listed on the National Register of Historic Places on May 1, 2017, and is undergoing an active restoration campaign.
