Gustav Meyrink (19 January 1868 – 4 December 1932) was the pseudonym of Gustav Meyer, an Austrian author, novelist, dramatist, translator, and banker, most famous for his novel The Golem. He has been described as the "most respected German language writer in the field of supernatural fiction."

The illegitimate child of a baron and an actress, Meyrink spent his childhood in Germany, then moved to what is today the Czech Republic, where he lived for 20 years. The city of Prague is present in most of his work, along with various religious, occult, and fantastic themes. Meyrink practiced yoga throughout his life.

Curiously, he unsuccessfully attempted to commit suicide at the age of 24. Tragically, his son succeeded in committing suicide at the same age. Meyrink founded his own bank but was accused of fraud, leading to a two-month imprisonment. He worked as a translator and translated 15 volumes of Charles Dickens into German while also working on his novels. Among his most famous works are Der Golem (1914) and Walpurgisnacht (1917).
