Jhumpa Lahiri is a prominent and leading literary figure on the horizon of Indian English literature. She is an expatriate writer, who has connected with homeland through her writings. She is one of the most outstanding novelists. ‘Search for identity’ plays a key role in her novels. Her novels are concerned mainly with social and political themes of the East-West Encounter. Her serious concern is with the cross-cultural consciousness of her characters. The keen observation of the life of immigrants and the interest in the study of their inner mind are proved by the portrayal of her characters. She gives a graphic picture of the theme of immigration and alienation of the uprooted individuals in her novel The Namesake (2003). The novel is based on the theme of immigration of native Indians who went to America; it deals with the theme of coloured immigrants in USA and presents their difficulties of adjustment there. This paper tries to focus the vision of masculinity and their dilemma such as search for identity, displacement, cultural dislocation, isolation and alienation in the novel.
