The article is devoted to the identification and analysis of conceptual metaphors that are involved in the implementation of the concept of "Longing" in the works of A. P. Platonov. The subject of the study is the metaphorical models of the concept under study. At the present stage of linguistic science, metaphors are presented as complex phenomena that are not only a fact of language, but reflect the mechanisms of human consciousness and ideas about the world. Conceptual metaphors are considered as a special tool of human cognition, having a culturally archetypal nature. The mechanisms of perception lie in the subconscious of a person, at the level of which there are units of the mental level – concepts represented to a greater extent by conceptual (cognitive) metaphors. Metaphorical models are one of the components of a concept and can be identified with the "signs of the concept that form its structure". The work is carried out in line with the cognitive campaign in linguistics, based on the research of conceptual metaphor. The following methods were used: continuous sampling, descriptive, contextual, modeling. The scientific novelty of the research consists in identifying metaphorical models of the concept of "Longing" in the discourse of A. P. Platonov. As a result of the study, 6 cognitive models of metaphors were identified: "Localization", "Living being", "Substance", "Object", "Organ", "Receptacle". These models represent the idea of the concept of "Longing" as an entity that has a location inside a person, more often it is the heart of a person. This entity is represented as a living being or object. At the same time, if longing is a living being, then a person cannot control it, but can only hide from it, and if longing appears as an object, then a person can manipulate it. Also, longing is thought of as a kind of container that can absorb a person.
