Orange Judd (July 26, 1822 – December 27, 1892) was an American agricultural chemist, editor, and publisher.

His grandfather, also named Orange Judd (1763–1844), came from Tyringham, Massachusetts and served as a private in the Berkshire Militia in the Northern Campaigns.

In 1850 he began studying analytical and agricultural chemistry at Yale for the next three years with John Pitkin Norton.

Judd championed the idea of clear and concise writing in journals, and was able to turn a paper of scientific jargon into something any literate farmer was able to understand.

Editors would obtain scientific material from colleges and would evaluate it and make it accessible for their readers.

[6] He was also one of the first people to practically apply opinion polls—sending out questionnaires on crop reports to his subscribers between May and September and publishing the results in the American Agriculturist.

[7] His success helped make American Agriculturist into one of the leading agricultural journals in the nation, going from a circulation 1,000 in 1856, to over 100,000 in 1864.

In 1871 the Orange Judd Hall of Natural Science was opened through his own work, and held the office of trustee from 1871 to 1881.

[5] In September 1888, The Orange Judd Publishing Company bought another agricultural journal, James Hill's The Farmer, which was in financial trouble.
