Esdras is an ancient Greek version of the biblical Book of Ezra in use among ancient Jewry, and the early church, and many modern Christians with varying degrees of canonicity. First Esdras is substantially the same as Masoretic Ezra, with one notable addition corresponding to the middle of Ezra Chapter 4.
The book was widely quoted by early Christian authors and it found a place in Origen's Hexapla. It was not included in canons of the Western Church. However, the use of the book continued in the Eastern Church, and it remains a part of the Eastern Orthodox canon.
