Harundale (pronounced HAIR-un-DALE) is an unincorporated community in Anne Arundel County, Maryland, United States.

[1] In 1947, the Byrne Organization made news when it set up a prefabrication shop on the 300-acre site and churned out parts for all 1,200 homes at once.

The houses featured welded steel frames which formed the basis of a structure using other materials.

Their construction marked the start of phenomenal post-World War II suburbanization of previously rural Anne Arundel County.

The Governor Ritchie Highway split the community into East and West sections.
