This study has been designed to analyze Samuel Beckett's late plays as representations of postmodern drama. Although Beckett's being a postmodern playwright is still discussed today, in this study it is analyzed that his late plays have much more in common with the features of postmodern drama. The concepts of metadrama, theatricality and performativity display themselves in the playwright's canon. The changes in the understanding of metadrama as creating multiple layers within a dramatic text, the concept of theatricality as nourishing the postmodern idea of the blurry relationship between real and unreal, and the theory of performativity that shows the inevitable function of language in the formation of the subject shape the analyses of Beckett's late plays in this study.
