The Church Street Historic District is a national historic district located in the village of Saranac Lake (Harrietstown) in Franklin County, New York.

It comprises twenty-seven buildings, including three churches, a medical laboratory, ten homes, two libraries, and six cure cottages, most built between the late 1870s and 1900.

Most of the buildings have features reflecting their use as cure cottages by residents suffering from tuberculosis.

Patients sat out on the "cure porches" in order to be exposed daily, year round, to as much fresh air as possible.
