Carley's Mills Schoolhouse

Carley's Mills Schoolhouse is a historic one-room school building located at Hastings in Oswego County, New York. It is a modestly scaled, one story frame building built about 1870. On the rooftop is a hipped roof belfry, which still retains what appears to be the original bell. Also on the property is a cast iron water pump. It ceased being used as a school in 1953.

It was listed on the National Register of Historic Places in 2005.
