The object: the collection of stories «Interpreter of Maladies» (1999), «Unaccustomed Earth» (2008), the novel «The Namesake» (2003). The goal of research: to determine the characteristics of hero`s transcultural identity`s representation in Jhumpa Lahiri`s writings.

The theoretical significance of the thesis is the development of problems related to Asian-American literature study and modern transcultural literature of the United States at the turn of the millennium, in particular in Jhumpa Lahiri`s writings. A complex interpretation of the writer's works is offered within the framework of national identity discourse and in transculture context. The practical value of the research lies in the fact that its main provisions can be used in further study and analysis of modern American literature in the context of transculture, in particular, during the study of Jhumpa Lahiri`s writings.

The scientific novelty of the research: an analysis of the study of Jhumpa Lahiri`s writings in transculture context and the problem of the hero`s identity was carried out for the first time in the Ukrainian literary criticism. Jhumpa Lahiri`s writings is viewed from the perspective of national identity. Novelty is also in the analysis of Indian and American elements` interaction in the writer's work. Jhumpa Lahiri`s writings should be considered not only in multiculturalism context. There is a symbolic «transition» from multiculturalism to transculture. The duality of Jhumpa Lahiri`s text is seen in the combination of Indian cultural code and American experience. A number of important Indian elements (symbols) that contributed to the formation of writer`s poetics of prose are pointed out for the first time: rice ceremony annaprazan, name`s duality (daknam, bhalonam), precedent phenomena. The field of use: scientific research in literary criticism and educational process.
