Eve (; Hebrew: חַוָּה‎‎, Modern: Ḥava, Tiberian: Ḥawwā; Arabic: حَوَّاء, romanized: Ḥawwāʾ; Greek: Εὕα, romanized: Heúa; Latin: Eva, Heva; Syriac: ܚܰܘܳܐ romanized: ḥawâ) is a figure in the Book of Genesis in the Hebrew Bible. According to the origin story of the Abrahamic religions, she was the first woman, yet some debate within Judaism has also given that position to Lilith. Eve is known also as Adam's wife.

According to the second chapter of Genesis, Eve was created by God (Yahweh) by taking her from the rib of Adam, to be Adam's companion. Adam is charged with guarding and keeping the garden before her creation; she is not present when God commands Adam not to eat the forbidden fruit – although it is clear that she was aware of the command. She decides to eat the forbidden fruit from the tree of the knowledge of good and evil after she hears the serpent's argument that it would not kill her but bring her benefits. She shares the fruit with Adam, and before they could eat of the tree of life, they are expelled from the Garden of Eden. Christian churches differ on how they view both Adam and Eve's disobedience to God (often called the fall of man), and to the consequences that those actions had on the rest of humanity. Christian and Jewish teachings sometimes hold Adam (the first man) and Eve to a different level of responsibility for the "fall."

The Catholic Church by ancient tradition recognizes Eve as a saint, alongside Adam, and the traditional liturgical feast of Saints Adam and Eve has been celebrated on 24 December since the Middle Ages in many European nations, including Estonia, Germany, Hungary, Lithuania, and the Scandinavian nations.
