1 Esdras, also Esdras A, Greek Esdras, Greek Ezra, or 3 Esdras, is the ancient Greek Septuagint version of the biblical Book of Ezra in use within the early church, and among many modern Christians with varying degrees of canonicity. 1 Esdras is substantially similar to the standard Hebrew version of Ezra–Nehemiah, with the passages specific to the career of Nehemiah removed or re-attributed to Ezra, and some additional material.

The Septuagint, sometimes referred to as the Greek Old Testament or The Translation of the Seventy, and often abbreviated as LXX, is the earliest extant Greek translation of the Hebrew Bible from the original Hebrew. The full Greek title derives from the story recorded in the Letter of Aristeas to Philocrates that "the laws of the Jews" were translated into the Greek language at the request of Ptolemy II Philadelphus by seventy-two Hebrew translators—six from each of the Twelve Tribes of Israel.
