Susanna, also called Susanna and the Elders, is a narrative included in the Book of Daniel by the Catholic Church, Oriental Orthodox Churches and Eastern Orthodox Churches. It is one of the additions to Daniel, placed in the Apocrypha by Protestants, with Anabaptists, Lutherans, Anglicans and Methodists regarding it as non-canonical but useful for purposes of edification. The text is not included in the Jewish Tanakh and is not mentioned in early Jewish literature, although it does appear to have been part of the original Septuagint from the 2nd century BC, and was revised by Theodotion, a Hellenistic Jewish redactor of the Septuagint text.

The Book of Daniel is a biblical apocalypse authored during the 2nd century BC, and set during the 6th century BC. The work describes "the activities and visions of Daniel, a noble Jew exiled at Babylon"; in doing so, it interpolates a portrayal of a historical prophecy being fulfilled with a prediction of future cosmic and political upheaval. This eschatology ultimately affirms that the God of Israel's previous deliverance of Daniel from his enemies prefigures his future deliverance of the people of Israel from their present oppression.
