Polyvios Vasiliadis (Greek: Πολύβιος Βασιλειάδης, Istanbul, 1922) was a Greek playwright and actor. In his early days, he collaborated with various magazines as a columnist and in 1952 he presented his first theatrical script. In 1957, he co-wrote his first script for the film "The Womanizer" with Nikos Tsiforos. The collaboration of the two men resulted in a total of 18 works. Vasiliadis, at the same time, created scripts for many other works (cinema, theater, video films) on his own. During the 70s and 80s, he collaborated with L. Michaelides and others.
