Josiah or Yoshiyahu ( /dʒoʊˈsaɪ.ə/ or /dʒəˈzaɪ.ə/; Hebrew: יֹאשִׁיָּהוּ, Yoshiyyáhu Yôšiyyāhû, literally meaning "healed by Yahweh" or "supported of Yahweh"; Greek: Ιωσιας; Latin: Josias; c. 649–609 BC) was a king of Judah (641–609 BC) who instituted major reforms. Josiah is credited by most historians with having established or compiled important Jewish scriptures during the Deuteronomic reform that occurred during his rule.

Josiah became king of Judah at the age of eight, after the assassination of his father, King Amon, and reigned for thirty-one years, from 641/640 to 610/609 BC.

He is also one of the kings mentioned in the genealogy of Jesus in the Gospel of Matthew.
