The Scarboro Landfill is a controversial landfill in Harford County, Maryland in the United States. It is located on the property of the Harford Waste Disposal Center operated by the Harford County Government where a separate sanitary landfill is in use. An assessment of the landfills was carried out and confirmed the concerns raised by local residents. The now closed Scarboro Landfill is unlined, and it received municipal waste from 1956 until 1986.
