According to the Book of Mormon, Aminadi (/əˈmɪn.ə.daɪ/) was a Nephite. Briefly mentioned in the Book of Alma, he is a descendant of Nephi, and an ancestor (through at least three generations) of Amulek.
During a speech to the people of Ammonihah, Amulek states that Aminadi was known as a prophet that had "interpreted the writing which was upon the wall of the temple, which was written by the finger of God."
