John Mills (c. 1717 – c. 1794) is an English writer on agriculture, translator and editor.

Mills and Gottfried Sellius are known for being the first to prepare a French edition of Ephraim Chambers's Cyclopaedia for publication in 1745, which eventually results in the Encyclopédie published in France between 1751 and 1772.

As writer on agriculture, Mills is credited for publishing the earliest complete treatise on all branches of agriculture.

His chief work, A New System of Practical Husbandry, in five volumes, appears in 1767.

It combines the results of the experience and observations of such writers as Evelyn, Duhamel, John Worlidge, and Jethro Tull, and is highly commended.

Mills is a warm advocate of small farms.
