Norfolk (/nɒr'fɒrk/)[3] is a town in St. Lawrence County in the U.S. state of New York.

A small part of Norfolk was lost when the community of "Raquetteville" incorporated as the Village of Potsdam Junction in 1869.

The Hepburn Library was listed on the National Register of Historic Places in 1969.

The Raquette River flows eastward through the northern part of the town.

New York State Route 420 parallels the eastern town line.

21.9% of all households were made up of individuals, and 11.1% had someone living alone who was 65 years of age or older.
