The Book of Azariah is a book by the Italian author and Roman Catholic mystic Maria Valtorta. It was written in 1946‑1947 in Viareggio, Italy where Valtorta was bedridden for several decades. The text is based on a a series of "dictations" which Valtorta attributed to her guardian angel, Azariah. In the book Valtorta does not provide a specific biblical reference to Azariah himself, but simply refers to him as her guardian angel. The name Azariah, from Hebrew, means God's help.
