Gothicism was one of the popular literary schools in the 18th and 19th centuries having a considerable impact on world literature. In Iran, some poets and writers have created works under the influence of Western literature written during Iran’s dark social history; one can include them in gothic literature. In Persian literature, Forugh Farrokhzad’s Let Us Believe in the Dawn of the Cold Season exemplifies gothic poetry. The poem is not just one of the most terrifying gothic poems in the Persian language but the saddest given its heartrending themes. One of its most significant features is its employing themes that demonstrate the frightening edge of existence and its resultant mental problems. Drawing on a descriptive-analytic approach and benefitting from library resources, the current study examines the gothic manifestations in Forugh Farrokhzad’s Let Us Believe in the Dawn of the Cold Season. According to the study’s results, the poem is dark, scary, and eerie in terms of its atmosphere; its emotional disorientation, supernatural components, prophesies, mental conflicts between the internal and external world, and wicked characters’ descriptions are compatible with the gothic genre.  By creating an environment appropriate for gothic features, the poet has created a textual creation that depicts surreal elements and can be classified in gothic literature. Hence, the poem’s contents blend dream and reality in an atmosphere of melancholy and distress. The poet begins her poem with loneliness, darkness, lamentation, and ghosts keeping her audience in a painful mood until the poem’s end.
