The Juvenile Instructor was a magazine for members of the Church of Jesus Christ of Latter-day Saints (LDS Church). It began publication in 1866 as a private publication, but by the late 1860s served as the de facto publication of the LDS Church's Deseret Sunday School Union organization.[1] It was an official periodical of the LDS Church from 1901 to 1929, after which the church replaced it with The Instructor.[2]
