Abigail was an Israelite woman in the Hebrew Bible married to Nabal; she married the future King David after Nabal's death. Abigail was David's third wife, after Ahinoam and Saul's daughter, Michal, whom Saul later married to Palti, son of Laish, when David went into hiding.

According to the 1st Book of Samuel Chapter 25, Nabal was a rich Calebite, described as harsh and surly. He is featured in a story in which he is threatened by David over an insult, and ultimately killed by God.
