Lot (/lɒt/; Hebrew: לוֹט Lōṭ, lit. "veil" or "covering"; Greek: Λώτ Lṓt; Arabic: لُوط Lūṭ; Syriac: ܠܘܛ Lōṭ) was a man mentioned in the biblical Book of Genesis, chapters 11–14 and 19. Notable events in his life recorded in Genesis include his journey with his uncle Abraham; his flight from the destruction of Sodom and Gomorrah, during which his wife became a pillar of salt. He is regarded as the parental ancestor of Ammonites and Moabites, the enemies of Israelites.

According to the Hebrew Bible, Lot was born to Haran, who died in Ur of the Chaldees. Terah, Lot's grandfather, took Abram (later called Abraham), Lot, and Sarai (later called Sarah) to go into Canaan. They settled at the site called Haran, where Terah died.

As a part of the covenant of the pieces, God told Abram to leave his country and his kindred. Abram's nephew Lot joined him on his journey and they went into the land of Canaan, settling in the hills of Bethel.

Due to famine, Abram and Lot journeyed into Egypt, but Abram pretended that his wife Sarai was his sister. Hearing of her beauty, the Pharaoh took Sarai for his own, for which God afflicted him with great plagues. When the Pharaoh confronted Abram, Abram admitted that Sarai had been his wife all along, and so the Pharaoh forced them out of Egypt.

When Abram and Lot returned to the hills of Bethel with their many livestock, their respective herdsmen began to bicker. Abram suggested they part ways and let Lot decide where he would like to settle. Lot saw that the plains of the Jordan were well watered "like the gardens of the Lord, like the land of Egypt," and so settled among the cities of the plain, going as far as Sodom. Likewise, Abram went to dwell in Hebron, staying in the land of Canaan.

The five kingdoms of the plain had become vassal states of an alliance of four eastern kingdoms under the leadership of Chedorlaomer, king of Elam. They served this king for twelve years, but "in the thirteenth year they rebelled." The following year Chedorlaomer's four armies returned and at the Battle of Siddim the kings of Sodom and Gomorrah fell in defeat. Chedorlaomer despoiled the cities and took captives as he departed, including Lot, who dwelt in Sodom.

When Abram heard what had happened to Lot, he led a force of three hundred and eighteen of his trained men and caught up to the armies of the four kings in Dan. Abram divided his forces and pursued them to Hobah. Abram brought back Lot and all of his people and their belongings.

Later, after God had changed Abram's name to Abraham and Sarai's name to Sarah as part of the covenant of the pieces, God appeared to Abraham in the form of three angels. God promised Abraham that Sarah would bear a son, and he would become a great and mighty nation. God then tells Abraham his plan,
