Reinhard Haupenthal (born February 17, 1945; died September 29, 2016) was a German Esperantist, Volapükist (or Volapükologist), translator, and linguist. Donald J. Harlow described Haupenthal's personal style in a warning to potential readers of Haupenthal's translation of Goethe's Young Werther: "the vocabulary used by Haupenthal is far from standard, and at times the Esperanto verges on the incomprehensible."
