Charley Klein (born Tiago-Charley) is a Swiss-Brazilian singer, songwriter, performer, and dancer. He adopted his stage name in 2018, inspired by being the youngest sibling and the playwright Charles Klein. Growing up between modest means and the middle class, he found refuge in music and film.

Currently studying film at HEAD – Geneva, Charley has been mentored by key cultural figures and trained as an acrobat at Cirque Starlight during his Sport-Art-Etude program in Porrentruy. A turning point came when he played Lancien in Les Demoiselles de Rochefort at Théâtre 14, leading him to complete a demanding program at EPCM in Paris.
