John Bennet Lawes (December 28, 1814 - August 31, 1900) was an English entrepreneur and agricultural scientist. He founded an experimental farm at his home at Rothamsted Manor that eventually became Rothamsted Research (oldest agricultural research facility in the world), where he developed a superphosphate that would mark the beginnings of the chemical fertilizer industry. He enlisted the services of Joseph Henry Gilbert, with whom he experimented for more than half a century in raising crops and feeding animals, activities which have rendered Rothamsted famous to scientific agriculturists.
