Andreas Sinopoulos is a painter. He was born in Athens in 1961, where he currently lives and works. He studied Painting at the School of Fine Arts – Department of Visual Arts of the Aristotle University of Thessaloniki, under the guidance of Makis Theofylaktopoulos. He also attended Engraving courses with Giorgos Milios and Art History with Niki Loizidi. He is a member of the Chamber of Fine Arts of Greece (EETE). Since 1999, he has been teaching at the Painting Workshop of the Municipality of Zografou in Athens. In 2007, he turned mainly to non-figurative painting, while remaining active in figurative art as well.

In January 2020, his body of work up to that point was presented at an event at IANOS bookstore by historian and architect Kostas Kazamiakis, with the participation of poet Giorgos Gotis and photographer Haris Kakarouchas. Between 1979 and 1982, he attended ASETEM-SELETE, studying Pedagogy. He has collaborated with painters and iconographers on church murals, with Kostas Georgakopoulos (1984), Chrysogonos Karahalios and Ioannis Christopoulos (1992–1994), and painter Kostas Papatriantafyllopoulos (2003–2004).

His special interest in East Asian art led him to study the Japanese language, in which he earned a degree in 1995. Since 2004, he has been researching the subject of the polychromy of ancient statues. He has presented his work in three solo and selected group exhibitions in Greece and Belgium from 1990 to the present. His works are held in private collections. In parallel with the visual arts, he has been involved in poetry since the 1980s, with several publications in well-regarded literary journals.
