Thrasos Kaminakis was born in Athens in 1964 and studied Law, Criminology, and Historical Nosology in Paris, where he lived until 1992. Under the guidance of important theorists and filmmakers such as Marc Ferro, Éric Rohmer, and others, he completed studies in Screenwriting and Film Direction.

He first appeared as a writer in 1984, winning first prize in a competition organized by the newspaper Ta Nea for his short story “Lemon Blossoms on the Iron Gates.” With this story, later adapted for the theatre, he entered theatrical directing in 1998. He has written mainly for the theatre: the trilogy 12 Months with 13 Moons, Moonweek, and The Moon in the Superlative; the one-act play collections The Women Whose Men Are Absent and Fragments of Bulimic Speech; the musical Dreamstreet; the episodic work The Seven-Day Cycle; the drama Blitz (in collaboration with Gogo Tsourou); and two theatrical fairy tales, The Circus Flies (with Eleni Konidari) and Lost Love Stories, for the band LSD, in 2009. He has also written songs for theatrical productions, with music by Dimitra Galani, Mode Plagal, Kostas Chatzopoulos, and others. He founded Pocket Theatre and organized the festival of the same name as well as the Story Telling Festival (2005–2014). He is the creator of Mikros Polytechneio in Thiseio, which he has directed since 2003. He teaches lyric writing, theatre writing, and creative writing. In 2018, his doctoral dissertation The Lazaretto of Syros was translated from French and published. His first book with Kastaniotis Editions, Three Eighteen, was published in 2022.
