Boaz is a biblical figure appearing in the Book of Ruth in the Hebrew Bible and in the genealogies of Jesus in the New Testament and also the name of a pillar in the portico of the historic Temple in Jerusalem. The word is found 24 times in the Scriptures, two being in Greek.

The Book of Ruth is included in the third division, or the Writings (Ketuvim), of the Hebrew Bible. In most Christian canons it is treated as one of the historical books and placed between Judges and 1 Samuel.
