Henry Allen "Harry" Ironside (October 14, 1876-January 15, 1951) was a Canadian-American Bible teacher, preacher, theologian, pastor, and author.
Ironside was one of the most prolific Christian writers of the 20th Century and published more than eighty books and pamphlets, many of which are still in print. As an editorial reviewer wrote of a 2005 republication, "Ironside's commentaries are a standard and have stood the test of time."
