"Jeremiah Pseudo" is the conventional name given to the unknown author or authors of Jewish religious texts written between the 3rd and 1st centuries BCE and falsely attributed to the ancient prophet Jeremiah. This was a period of significant Jewish literary activity following the translation of the Hebrew scriptures into Greek.

The primary surviving work is the Epistle of Jeremiah. This short text, which appears as part of the Book of Baruch in the ancient Greek Septuagint translation, is presented as a letter from the prophet to Jewish exiles. It is a forceful argument against idolatry and an affirmation of monotheistic belief. Modern scholars uniformly regard it as pseudepigraphical, meaning it was composed centuries after the prophet's life by an anonymous writer using his name for authority.

These writings are significant for understanding Jewish theological development during the Second Temple period. The Epistle of Jeremiah illustrates how Jewish authors engaged with and rejected elements of the surrounding Hellenistic culture. Its inclusion in the Greek Bible also made it an influential text for early Christian communities, highlighting the complex history of how biblical books were collected and canonized.
