Lonaconing is a town in Allegany County, Maryland, United States, located along the Georges Creek Valley.

The first non-Native American settlers in the late 18th century were explorers, hunters and farmers.

The first stone house, built in 1790, in Knapps Meadow, just north of Lonaconing, was owned by Samuel VanBuskirk.
