John Fillmore Hayford (May 19, 1868 – March 10, 1925) was an eminent United States geodesist.

His work involved the study of isostasy and the construction of a reference ellipsoid for approximating the figure of the Earth.

The crater Hayford on the far side of the Moon is named after him.

Mount Hayford, a 1,871m mountain peak near Metlakatla, Alaska, United States, is named after him.

A biography of Hayford may be found in the Biographical Memoirs of the National Academy of Sciences, volume 16(5), 1935.
