This is what the Bible says about Noah's wife beginning in Genesis 7:7, "So Noah, with his sons, his wife, and his sons’ wives, went into the ark because of the waters of the flood."
The Bible does not give her name, however, according to Jewish tradition her name is Naamah - the sister of Tubal-cain, a descendant of Cain, the son of Adam and Eve (see Genesis 4:22). Why Tubal-cain's sister (a daughter of Lamech by his wife Zillah) should be specifically mentioned is unknown. Jewish tradition made her Noah's wife. Her name, meaning "the beautiful" or "the pleasant one," reflects the worldly mind of the Cainites, who looked for beauty rather than for character as the chief attraction in women.
