Heiner Müller (] ; January 9, 1929 – December 30, 1995) was a German (formerly East German) dramatist, poet, writer, essayist and theatre director.  Described as "the theatre's greatest living poet" since Samuel Beckett, Müller is arguably the most important German dramatist of the 20th century after Bertolt Brecht.  His "enigmatic, fragmentary pieces" are a significant contribution to postmodern drama and postdramatic theatre.

Hamletmachine (in German, Die Hamletmaschine) is a postmodernist drama by German playwright and theatre director Heiner Müller.  Written in 1977, the play is loosely based on "Hamlet" by William Shakespeare.  The play originated in relation to a translation of Shakespeare's "Hamlet" that Müller undertook.  Some critics claim the play problematizes the role of intellectuals during the East German Communism area; others argue that the play should be understood in relation to wider post-modern concepts.  Characteristic of the play is that it is not centred on a conventional plot, but partially connects through sequences of monologues, where the protagonist leaves his role and reflects on being an actor.
