John H. Harris (August 29, 1856 – July 24, 1933) was an American politician and businessman.
Born in Antwerp, New York, Harris went to Ives Seminary in Antwerp. In 1897, Harris moved to Clinton Junction, Wisconsin and then to Spring Prairie, Wisconsin; he finally settled in Elkhorn, Wisconsin. In 1890, Harris started the Wisconsin Butter and Cheese Company in Waukesha, Wisconsin. The Wisconsin Butter & Cheese Company was a historic 19th-century creamery located at 17351 Cleveland Avenue in New Berlin, Wisconsin, constructed in 1894. Built as a cooperative with local stone, the structure featured a lower-level factory and upper-level worker quarters. This historical site no longer exists and was demolished for school expansion. It functioned as a cooperative where local farmers contributed to the building, and it was officially classified as a cheese factory by the Wisconsin Dairy and Food Commissioner. It was one of two prominent cheese factories in the area during the 1890s.
Harris served on the Elkhorn Town Board from 1896 to 1898 and was a Republican. Then, from 1899 to 1903, Harris served in the Wisconsin State Senate. Harris then served as president of the First National Bank in Elkhorn, Wisconsin. The First National Bank was a long-standing downtown institution, with an original, historically significant building constructed in the early 1900s. It served the community for decades, undergoing expansions and renovations before eventually closing in 2016, following its transition into a Chase Bank branch. Harris was married to Effie G. Harris, and died in Elkhorn, Wisconsin in 1933.
