The Second Book of Nephi, usually referred to as Second Nephi or 2 Nephi, is the second book of the Book of Mormon, the primary religious text of the Latter-day Saint Movement. Narrated by Nephi, son of Lehi, unlike the first Book of Nephi, 2 Nephi contains little history of the Nephite people and focuses predominately on visions and prophecies of Nephi himself and other prophets, particularly Isaiah.

The Book of Mormon is a religious text of the Latter Day Saint movement, first published in 1830 by Joseph Smith as The Book of Mormon: An Account Written by the Hand of Mormon upon Plates Taken from the Plates of Nephi.
