The present study aimed to analyze the postmodern features of Slaughterhouse-Five , authored by Kurt Vonnegut, and its two Persian translations by Bahrami and Abbasi. To this end, Lewis’s classification of postmodern features (2011) and Parham’s model (2015) were employed. The features investigated in this study were temporal disorder, fragmentation, vicious circles, paranoia, reader involvement, polyvocality, pastiche, and intertextuality. The results indicated that most postmodern features were preserved in both translations. However, the absence of several fragmentations and intertextuality features in Persian translations can imply the translators' unawareness of the significance of translating these features. To translate these features into the target text, translators should be aware of their impacts on the text, content, and audience. To translate postmodern features more precisely, it is suggested that postmodern features be taken into consideration by literary translators and translator trainers. The findings of this research can have implications for literary translators, and literary translation classrooms.
