Lyman Eugene Johnson (October 24, 1811 – December 20, 1859) was an early leader in the Latter Day Saint movement and an original member of the Quorum of the Twelve Apostles. He broke with Joseph Smith and Sidney Rigdon during the 1837–38 period when schism divided the early church. Johnson later became a successful pioneer lawyer in Iowa and was one of the town fathers of Keokuk, Iowa. Johnson died in 1859, drowning in the Mississippi River in a carriage accident at Prairie du Chien, Wisconsin. He had at least five children.
