Salter's Mill is a historic gristmill built c. 1897 and located at 33 Imlaystown Road in the Imlaystown section of Upper Freehold Township in Monmouth County, New Jersey.

It was added to the National Register of Historic Places on September 29, 1980, for its significance in agriculture, architecture, and exploration/settlement.

It was badly damaged by a fire in 1897 and the current mill was built soon afterwards.

The two and one-half story frame building has a horizontal turbine wheel.

The last owner was the Golden family, who closed mill operations in 1962.
