The Parshah is named "Noach" (Noah) after the protagonist of its major event: The Great Flood. It is found in Genesis 6:9.

G‑d instructs Noah—the only righteous man in a world consumed by violence and corruption—to build a large wooden teivah (“ark”), coated within and without with pitch. A great deluge, says G‑d, will wipe out all life from the face of the earth; but the ark will float upon the water, sheltering Noah and his family, and two members (male and female) of each animal species (and 7 of the "pure" species).
