This is the name of a man. See 1 Samuel 21:7. Doeg tells Saul that Ahimelech the priest gave David food and a sword and prayed for him. Saul accuses the priests of encouraging David to rebel. This is a serious accusation because the priests are God's representatives and are rebelling against God's king if true. Saul has the priests and all their families killed except those who escape to David.
