约书亚，是《旧约圣经》记载的一个希伯来人领袖，是嫩的儿子；属以法莲支派，原名何希阿。

据《圣经·申命记》所载，约书亚继摩西成为以色列人的领袖，带领以色列人离开旷野，进入应许之地迦南。最初由埃及出发的以色列成年男子，只有约书亚与迦勒得以活着进入迦南。其余埃及出生的成年男子，均因犯罪，为神所憎，而中途死于旷野。其余进入迦南的以色列人，均为旷野出生。

在约书亚的领导下，以色列人在许多战争中获得了辉煌的胜利，占领了以色列地区一带土地，也就是古代迦南人、赫人、亚摩利人、比利洗人、希未人、耶布斯人的地方，是流奶与蜜之地。

Joshua /ˈdʒɒʃuə/ or Jehoshua (Hebrew: יְהוֹשֻׁעַ Yĕhôshúʿa or Hebrew: יֵשׁוּעַ Yĕshúʿa; Aramaic:ܝܫܘܥ‎ Isho; Greek:Ἰησοῦς, Arabic:يوشع بن نون‎ Yūshaʿ ibn Nūn; Latin:Iosue, Turkish:Yuşa) is a figure in the Torah, being one of the spies for Israel (Num 13–14) and identified in several passages as Moses' assistant. He is the central figure in the Hebrew Bible's Book of Joshua. According to the books of Exodus, Numbers and Joshua, he became the leader of the Israelite tribes after the death of Moses. His name was Hoshe'a (הוֹשֵׁעַ) the son of Nun, of the tribe of Ephraim, but Moses called him Yehoshu'a (יְהוֹשֻעַ; Joshua in English) (Numbers 13:16) the name by which he is commonly known. The name is shortened to Yeshua in Nehemiah (Nehemiah 8:17). According to the Bible he was born in Egypt prior to the Exodus.
