Mount Adams, also known as The Mount, is a historic home and farm complex located at Bel Air, Harford County, Maryland, United States. The complex consists of a 114-acre (46 ha) working farm, originally part of Broom's Bloom, centered on a large, multi-sectioned, 2+1⁄2-story frame house built in 1817 in the Federal style. The house has an 1850, 2+1⁄2-story cross-gabled addition, connected, but an independent unit from the main house, and slightly taller in the Greek Revival style. The property include a stone bank barn, a stone-and-stucco dairy, a stone-and-stucco privy, all dating from the early 19th century, as well as a family cemetery. Its builder was Captain John Adams Webster.

Mount Adams was listed on the National Register of Historic Places in 1988.
