This thesis explores the notion of diasporic identity in the fiction of Junot Díaz. Looking at the Dominican diaspora of the 1960, as well as the African diaspora of the colonial era, in this thesis I analyse the presence of diasporic identity as well the larger overall effects of the diaspora on Díaz's most prominent characters, concerning the way they exhibit the characteristics of a diasporic identity and the role the English and Spanish language play in regard to the Dominican diaspora. This thesis also looks at the effect of conflicting gender roles within the Dominican diaspora and at the lasting presence of the African diaspora, a remnant of the colonial history of the Dominican Republic.This thesis explores the notion of diasporic identity in the fiction of Junot Díaz.
