John Steele (1821-) was an Irish convert to the Church of Jesus Christ of Latter-day Saints that immigrated to the United States in 1845.

John Steele was born 21 March 1821 in Hollywood, Ireland, to John and Nancy Steele. In his fifteenth year, Steele began apprenticing as a boot and shoe cobbler, soon opening his own shop in Belfast. John married Catherine Campbell at the age of nineteen. On 10 April 1842, John Steele was baptized into The Church of Jesus Christ of Latter-day Saints, followed approximately one month later by his wife Catherine. Soon after the death of their infant daughter Margaret, Steele and his wife decided to take their two surviving children and immigrate to the United States.

Upon arriving in New Orleans harbor on 7 March 1845, the Steele family traveled by steam ship up the Mississippi River and joined their fellow Saints in Nauvoo, Illinois. Slightly over one year later, on 4 May 1846, John and his family left Nauvoo, and with other church members, headed for Council Bluffs, Iowa. After serving in the Mormon Militia and traveling throughout the western United States, John Steele and his family, which had grown by that time to include five children, settled in Toquerville, Utah. Up until his death on 31 December 1903, John Steele was an active member of the LDS Church, serving a British Mission in 1877-78, acting as the Bishop of Parowan, Utah, and assisting in the construction of the Manti Temple.
