Oak Lea is a private home of 19th-century origin in the Layhill community of Montgomery County, Maryland, described as "the gracious culmination of architectural and building efforts dating back well over a hundred years.

"[1] The house is composed of three adjoined blocks built at different times:[2] A log smokehouse and a frame bank-barn with a stone foundation were originally located to the west of the house,[2] dating from the property's original agricultural use.

[3][4][5] Additions of three log rooms were the only major changes made in the structure until the house was renovated in 1940.

[7] In the early mid-20th century, Oak Lea was the home of noted Maryland golfer Roland MacKenzie.

[8] Oak Lea was nominated for the National Register of Historic Places in 1974.
