Whiteford-Cardiff Historic District is a national historic district at Cardiff and Whiteford, Harford County, Maryland, United States. It encompasses portions of two communities in northern Harford County that were historically associated with slate production during the late 19th and early 20th centuries. It contains 140 contributing resources including four vernacular Welsh cottages dating to about 1850. The Whiteford-Cardiff area is noted for its strong Welsh ethnic identity, which is reflected in the architecture of the area.

It was added to the National Register of Historic Places in 2005.
