Riverside is a census-designated place (CDP) in Harford County, Maryland, United States.

[2] The term "Riverside" is generally used interchangeably with "Belcamp"; both names are accepted for the U.S.

However, the original community of Belcamp is located south of U.S. Route 40, outside the Riverside CDP.

Bel Air, the Harford County seat, is 8 miles (13 km) northwest of Riverside via MD 543.

All commercially zoned property is located off Route 543, also known as the Riverside Parkway.

A business park built on Route 40 at the former site of the Bata Shoes factory opened in 2000 and originally provided offices for Clark Turner Signature Homes and SURVICE Engineering.

Expansion to the business park has brought in Booz Allen Hamilton and SafeNet.
