The Books of the Kingdoms, Books of Kingdoms, or Books of Reigns () are the names that four books of the Hebrew Bible are given in the Septuagint. 1 and 2 Kingdoms are equivalent to 1 and 2 Samuel, and 3 and 4 Kingdoms are equivalent to 1 and 2 Kings in most modern English versions.
These books are known in the Vulgate version as the four Books of the Kingdoms ( or ), or the Book of Kings () as Jerome disagreed with the expression Books of the Kingdoms () of the LXX. Jerome says:
Those books are known as the Books of Reigns in the New English Translation of the Septuagint.
