William M. Ireland (died December 24, 1891) was one of the eight founders of the National Grange of the Order of Patrons of Husbandry, a fraternal organization in the United States.

[1] He was an avid Freemason, Ireland added valuable knowledge to organizational systems and methods in the formative period of the Grange movement.

His ability to be a critic and adviser in setting up the work of the Grange created a balance of knowledge and inspiration.

[3] Ireland was responsible for the publication of The Journals of Proceedings for the organization and compiled ten annual sessions from 1875 to 1883.

At the twelfth session of the Grange, Ireland was elected to fill the remaining term as secretary and was re-elected three times afterward.
