Abraham Owen Smoot (1815–1895) was a Mormon pioneer, mayor of both Salt Lake City and Provo, Utah, and an early supporter of Brigham Young Academy.

Abraham Owen Smoot was born February 17, 1815, to George W. Smoot and Ann Rowlett of Owenton, Kentucky. His father died when he was young, after which his mother remarried and moved the family to Tennessee. Here he was converted and baptized into The Church of Jesus Christ of Latter-Day Saints in 1835 at the age of 20; he was given immediate stewardship over the small branch of the Church there in Benton County. In February of the following year, he went on a mission to Kentucky and Tennessee. In 1837, he moved to western Missouri, and in 1838 he was called on a proselyting mission to southern Missouri and Arkansas. During this time, as Mormons were being driven out of Missiouri, he fought in the Missouri Mormon War in Far West. On November 11, 1838, in the aftermath the siege, Smoot married Maragret Thompson McMeans. Over the course of his life, he took five additional wives: Sarah Gibbens and Emily Hill in 1846, Diana Caroline Tanner Eldredge in 1855, Anne Kristine Mauritzen in 1856, and Hannah Caroline Rogers in [date unknown]. He had twenty-seven children, three of whom were adopted. He was called on another mission to South Carolina in August 1841, returning in July 1842. He led the Keokuk branch for a while before leaving on another mission, to Alabama, in 1844.

Smoot led companies of Church members to the Salt Lake Valley in 1847, 1852, and 1856. He served as a councilman in Sugarhouse from 1854-1857, then became mayor of Salt Lake City, serving until 1866. He stepped down when he received a call as president of the Provo Utah Stake. In Provo, he was again elected mayor, serving from 1868-1881. He was a major investor in Provo Wollen Mills, cofounder of a bank and a lumber company, and first head of the board of trustees of Brigham Young Academy (now Brigham Young University). He is credited with making major financial contributions that allowed the Academy to continue functioning, and BYU's administration building bears his name today.

He died in Provo on March 6, 1895.

Abraham Owen Smoot II (1856-1911) was an Mormon missionary, businessman in Provo, Utah, and son of the Utah pioneer A. O. Smoot.

Abraham Owen Smoot II was born on March 11, 1856 in Salt Lake City, Utah, to Abraham Owen Smoot and Diana Tanner Eldredge. When Abraham was eleven years old his family moved to Provo, Utah, where his father was serving as town mayor and stake president of the Utah Stake of the Church of Jesus Christ of Latter-day Saints. As a youth Abraham attended Brigham Young Academy under the tutelage of Karl G. Maeser, and was among the first to graduate from that institution. At the age of seventeen Abraham and his friend, William Paxman, started their own business, the Paxman & Smoot Lumber Company.

At the age of nineteen Abraham was called to serve a mission to Great Britain for the Church of Jesus Christ of Latter-day Saints. After arriving in England, Abraham was assigned to the London Conference and served as its unofficial clerk and secretary. His friend from home, William Paxman, presided over the conference, and the two worked together as companions for much of their missions.

After returning from Great Britain, Abraham married Electa Bullock, also from Provo, in Salt Lake City on October 30, 1878; they were blessed with six children, two sons and four daughters. He returned to the lumber business and managed the newly-formed Smoot Lumber Company until 1896. During this time he also served as county assessor for eight years and as a representative to the upper house of the territorial legislature for one term. Tragically, Electa died in 1887 at the young age of twenty-eight; Abraham remarried in 1893 to Zina A. Huntington, who bore him one daughter.

After Utah gained its statehood, Abraham was elected to the state house of representatives for one term and to the state senate for two terms. In this latter position he occupied the post of floor leader for the Democratic Party, and initiated new legislation on inheritance, railroads, and other issues. He also at various times served as Provo City councilman, secretary of the Territorial Insane Asylum, United States commissioner, and trustee for the State Agricultural College. Ecclesiastically, he held the callings of home missionary and high councilman for the Utah Stake. On May 22, 1911, Abraham Owen Smoot II suddenly passed away from uremic poisoning after a throat operation in the local hospital in Provo, Utah.
