Animus refers to elements of masculine characteristics and masculine movements that are more or less present in women's personalities. These traits have also been formed in the subconscious of women over time and through centuries and the mixing of men and women. Animus has positive and negative manifestations that have been deposited in the subconscious of humans, both women and men, throughout human history. This research examines and analyzes the manifestations of animus in Parvin Etesami's poetry. The purpose of the research is to conduct a comparative analysis of the archetype of animus in Parvin Etesami's poetry based on Carl Gustav Jung's theory, a case study of a fragment of a letter to Noshirvan. The research method is descriptive-analytical and library-based. The research findings show that in the collective unconscious of Parvin Etesami and her inner male part, regardless of the characteristics of a ruler, there are characteristics and characteristics of an animus such as decisiveness, fairness, compassion, forgiveness, and support. Of these characteristics, compassion and support, which are among the most important characteristics of the animus, have a high frequency in the letter to Noshirvan.
