Uluka or Ulook was the son of the King of Gandhara, Shakuni and Arshi in the Mahabharata. Before the Pandavas come back from their anonymity he wanted to take Shakuni back to Gandhara but Shakuni refused and stayed in Hastinapura to bring the war of Mahabharata. He was killed by Sahadev in the Kurukshetra war. He was sent by the Kaurava prince Duryodhan to the Pandav camp the day before the great war of Kurukshetra started, to insult all the warriors supporting the Pandavas. Having listened to Uluka’s words, Yudhishthira, the son of Kunti, moved his army headed by Dhrishtadyumna and others.
