Cottage Row Historic District is a national historic district located in Saranac Lake (Harrietstown) in Franklin County, New York. It includes 27 contributing privately owned single-family dwellings built between 1900 and 1940, with the majority constructed between 1907 and 1917. They are mostly two- or three-story, wood-framed structures, with gable or gambrel roofs, dormers, and wood siding or shingles. Most of the residences were operated as commercial, private tuberculosis sanitorium, with characteristic architectural features of the "cure cottage," including second story sleeping porches, extra wide doorways, and call bell systems.
