Coriantum is a character in the Book of Mormon's Book of Ether. Like his father, he was a righteous ruler of the Jaredites. He was noted for being exceedingly righteous, even to the point that he was blessed to see the Son of Righteousness. Coriantum's wife was barren. At 102 years of age, however, she passed away. Coriantum then married a 'young maid' who bore him children. One of these was Com, whom he conferred the kingdom on. He passed away after living to 142 years of age.
