Choni HaMe'agel ("the circle-drawer") was a Sage of the Land of Israel renowned as a miracle worker, a contemporary of Shimon ben Shetach in the period of the Zugot, in the 1st century BCE.

The Mishnah relates that one year most of the month of Adar passed without rain. Choni was asked to pray; he prayed, but no rain came. He then drew a circle, stood inside it and swore by God's great Name not to move until He had mercy on His children. A few drops began to fall; Choni said this was not what he had asked for, but rain to fill cisterns, ditches and caves. Then came a violent downpour, and he specified again: rains of goodwill, blessing and generosity, and the rain finally fell as it should. Shimon ben Shetach sent word that he deserved to be excommunicated, but that he behaved before God like a pampered son whose father grants his wishes, and applied to him the verse "Let your father and mother rejoice."

The Babylonian Talmud tells that he saw a man planting a carob tree that would bear fruit only after seventy years; the man answered: "Just as my fathers planted for me, I plant for my children." Choni dozed off and awoke seventy years later to see the man's grandson gathering the carobs. In the study hall no one believed he was Choni; grieved, he prayed for death and died. Rava drew from this the saying: "Either companionship or death." Josephus gives another account: having refused to pray against Aristobulus during the siege of Jerusalem, he was stoned. His grandsons Abba Chilkiyah and Chanan HaNechba were also righteous men whose prayers were answered in times of drought.

Several traditions locate his tomb: in Jerusalem, in Alma, and above all near Par'am, today Chatzor HaGlilit, where he is said to rest with his wife and sons, near the cave of his grandsons. His hilloula is held there every year.
