The archetype of the anti-hero has appeared in postmodern poetry in different forms, especially "Anima", "Animus" and "Self" so boldly and diversely that Sometimes it makes the reader feel doubt and confused in distinguishing the hero from the anti-hero.the current research, using the descriptive-analytical method, has tried to determine the position and function of the archetype of the anti-hero in the course of postmodern poetic narration. The results of this study showed that postmodern poets are praised as long as the archetype of the anti-hero protests against the social conditions, and he is praised among the heroes, but when this role causes Damage to one's own archetype or other positive archetypes is no longer supported.
