Leo Birinski (June 8, 1884 – October 23, 1951) was a playwright, screenwriter and director. He worked in Austria-Hungary, Germany and in the United States. As a playwright in Europe, he gained his biggest popularity from 1910 – 1917 but was ultimately forgotten. From the 1920s to 1940s he worked mainly as a screenwriter, first in Germany, later in the United States, to which he emigrated in September 1927. In the United States, he also returned to writing stage plays. He wrote in German and English. Until recently, only a minimal amount of information about his life has been available. Complicating matters, there have been many legends and rumours concerning Birinski's person, including the false report of his "suicide" in 1920 that found its way from newspaper obituaries into encyclopedia
