Bernard Herman Schettler (1833-1907) was a German immigrant and Mormon convert in Utah.

Bernard Herman Schettler was born January 19, 1833 in Neuwied, Prussia (now Germany) to parents Frederick August Schettler and Caroline Louise Zipperlen. His childhood was marked by recurring health problems that caused him constant pain and an unsuccessful back surgery that left Schettler permanently disfigured for the rest of his life. Schettler's father died in 1850 and seventeen-year-old Schettler had to take over his family's finances until he emigrated to the United States in 1853. In 1860, while living in New York City, Schettler was baptized into The Church of Jesus Christ of Latter-day Saints by Apostle George Q. Cannon despite his mother's fear and disapproval. He often hosted many missionaries in his home, including prominent members of the Church such as Orson Pratt and Erastus Snow.

In 1861, Schettler left New York City, crossed the plains, and settled in Salt Lake City, Utah. Once he arrived, he had the occasion to meet President Brigham Young, leader of The Church of Jesus Christ of Latter-day Saints and Young gave him a job working in his office as a clerk; he also worked as a clerk at ZCMI and started a banking business. Schettler had six wives: Martha Wallace, Mary Morgan, Sally Taylor, Elizabeth Parry, Agatha Peters, and Susan Maria Moore. He had a total of nineteen children plus one child who he and his first wife adopted from South Africa. In 1888, he was arrested and imprisoned for participating in polygamy, but was released after six months in jail and paying a large fine.

Schettler died on October 27, 1907 at Salt Lake City.
