Ben Sira, also called Ben Sirach, Jesus ben Sira, Joshua ben Sira, or Sirach (Hebrew: שמעון בן יהושע בן אליעזר בן סירא, romanized: šimʿon ben yəhošuʿ ben ʾəliʿezer ben Sirā; fl. 2nd century BCE) was a Hellenistic Jewish scribe, sage, and allegorist from Seleucid-controlled Jerusalem of the Second Temple period. He is the author of the Book of Sirach, also known as "Ecclesiasticus".
Ben Sira wrote his work in Hebrew, possibly in Alexandria in the Ptolemaic Kingdom c. 180–175 BCE, where he is thought to have established a school.
