John Adlum (April 29, 1759 – March 14, 1836) was a pioneering American viticulturalist who was the first to cultivate the Catawba grape. He is known as "the father of American viticulture" (grape-growing). He also served in the American Revolutionary War; was a well-known surveyor; was one of the first associate judges in Lycoming County, Pennsylvania; and served in the United States Army in the War of 1812.
