Decla-Film (later Decla-Bioscop after 1920) was a German film production and distribution company of the silent era, founded by Erich Pommer and Fritz Holz in February 1915.
It was formed out of the assets of the German branch of the French film production company Éclair, Deutsche Éclair, which had been confiscated by the German government at the start of World War One. Pommer had previously been director of the Austrian branch of Éclair in Vienna. The firm merged with Deutsche Bioskop AG in Spring 1920, and with Ufa in October 1921.
Decla and Decla-Bioscop produced some of the most well-known films of the Weimar era, including Homunculus, Die Pest in Florenz, The Spiders, The Cabinet of Dr. Caligari, Destiny, Phantom and Die Nibelungen.
