The Bowlus Mill House is a historic home and farm complex, located at Spoolsville, Frederick County, Maryland, United States.

It consists of the house built of narrow courses of flat cut stones, a frame bank barn on a stone foundation, and a small frame shed.

The 2+1⁄2-story house with an exposed basement was built about 1800, and reflects the Germanic influence typical of the region in the period.
