The John Whitmer Historical Association (JWHA) is an independent, nonprofit organization promoting study, research, and publishing about the history and culture of the Latter Day Saint movement. It is especially focused on the Community of Christ, other midwestern Restoration traditions, and early Mormonism. The Community of Christ's approach to its own history was influenced, in part, by historical problems raised and explored through JWHA publications and conferences, and those of its sister organization, the Mormon History Association. JWHA membership numbers around 400 and is open to all, fostering cooperation with LDS and non-Mormon scholars.

Leonard James Arrington was an American author, academic and the founder of the Mormon History Association. He is known as the "Dean of Mormon History" and "the Father of Mormon History" because of his many influential contributions to the field. Since 1842, he was the first non-general authority Church Historian for the Church of Jesus Christ of Latter-day Saints, from 1972 to 1982, and was director of the Joseph Fielding Smith Institute for Church History from 1982 until 1986.
