Delaware County Christian School (also known as "DCCS" or just "DC") is a PK2 to 12 independent, coeducational, interdenominational day school with an enrollment of approximately 820 students located on two campuses in Newtown Square and Devon, Pennsylvania in the United States. The school's official mission is "to educate students who will serve God and impact the world through biblical thought and action."

Originally only at the Malin Road campus on the grounds of the George W. Strawbridge, Jr. estate, it expanded in 1968 with the purchase of the Alice Grim school at Bishop Hollow Rd. and West Chester Pike for grades K-5. In 2009, DC made an arrangement with The Episcopal Academy to exchange campuses which allowed DC to move the Elementary program to the more spacious and accommodating facility in Devon, PA.

Until 2007, DC was a member of the Southern Chester County League (SCCL). Almost the entire SCCL was absorbed into the Ches-Mont League except for Garnet Valley High School, Devon Preparatory School, and DC (the latter two were the league's smallest members). For the 2008-2009 academic year DC, joined the Bicentennial League rejoining former SCCL rival Devon Prep. The school's mascot is The Knight and its colors are green and white. The Varsity boys lacrosse team is currently a part of the Tri-County League.
