Mount Airy, also known as Grove Farm, is a historic home located at Sharpsburg, Washington County, Maryland, United States.

It is a 2+1⁄2-story Flemish bond brick house, built about 1821 with elements of the Federal and Greek Revival styles.

Also on the property are a probable 1820s one-story gable-roofed brick structure that has been extensively altered over time, a late-19th-century frame barn with metal roof ventilators, a 2-story frame tenant house built about 1900, and a mid-20th-century cinder block animal shed.

On October 3, 1862, President Abraham Lincoln and General George McClellan visited Mount Airy, an event recorded photographically by Alexander Gardner.
