Mount Athos is a historic archaeological site located at Kelly, Campbell County, Virginia.

It consists of a stone ruin atop a wooded ridge overlooking the James River.

The property was originally owned by John Bolling (1700–1757), and was part of a larger tract of land called Buffalo Lick.

Lewis built a plantation house there about 1800, a one-story dwelling with a classical portico and polygonal projections inspired by the architecture of Thomas Jefferson, of whom Lewis was a friend.
