Martin Andreas Hainz (born 5 March 1974 in Vienna, Austria) is an Austrian philologist, theorist and philosopher.
His main interests are contemporary Austrian philosophy and literature.
Hainz's works deal with Paul Celan and Rose Ausländer as well as Friedrich Gottlieb Klopstock; he is also considered to be one of today's most important advocates of Jacques Derrida's deconstruction.
Hainz has done research into some obscure authors and thinkers, such as Leopold von Sacher-Masoch, Alfred Margul-Sperber and Constantin Brunner.
His book Vom Glück sich anzustecken (About the luck of getting infected), about translation, has been discussed intensely, with Vincent Kling calling it "beyond praise" in a review.
