Luke Johnson (November 3, 1807 – December 9, 1861) was a leader in the Latter Day Saint movement and an original member of the Quorum of the Twelve Apostles from 1835 to 1838. He served in the Quorum with his younger brother, Lyman E. Johnson, and Orson Hyde, his brother-in-law. Johnson was born November 3, 1807, in Pomfret, Vermont, a son of John Johnson and Elsa Jacobs. He wrote of his family in an autobiographical sketch: Johnson was an educator and a physician. He married Susan H. Poteet on November 1, 1833. This marriage produced six children: Elisa Mary, Fanny, Eliza, Vashtia, James, and Solomon. After Susan's death on September 20, 1846, he married America Morgan Clark on March 3, 1847, in Council Bluffs, Iowa, and had additional children. This family included Susan Marinda, Orson Albert, Mark Anthony, Charlotte Elizabeth, Lovinia Ann, Phebe W. and Luke.

By October 1831, he had been ordained an elder and went on a mission to southern Ohio with Robert Rathburn.

Their efforts brought about fifty new members into the young church, including Rigdon's mother and other members of the Rigdon family. At one point, while he was praying, he had a vision of both the Angel Moroni and the golden plates. Johnson was ordained to the office of high priest by Smith on October 25, 1831. With Seymour Brunson and Hazen Aldrich, he served as a missionary in Ohio, Virginia, and Kentucky in 1832 and 1833, baptizing more than a hundred people on their journey. He was a member of the Kirtland high council which was formed on February 17, 1834. On June 26, 1834, Johnson marched with Zion's Camp, suffering with cholera on the journey. At age 27, Johnson was chosen and ordained one of the original members of the Quorum of Twelve Apostles on February 15, 1835. Shortly after the quorum was formed, the new apostles were sent on missions. Johnson served in the Eastern United States, New York and Upper Canada. He returned to Kirtland, Ohio, in late 1836. There, he attended Hebrew school and the Kirtland Temple. Johnson defended Smith from criticism on several occasions. But, in 1837, he became alienated from Smith, in
