Thomas Rowell "Tom" Leavitt (June 30, 1834 May 21, 1891) was an member of The Church of Jesus Christ of Latter-day Saints and the founding settler of Leavitt, Alberta, Canada, which the former Utah sheriff and marshal founded at age 53 after an arduous 800 miles journey in covered wagons, fleeing a crackdown on polygamy that sent fellow members of The Church of Jesus Christ of Latter-day Saints across the border to Mexico and Canada.
