Konstantinos Th. Spyropoulos (b. 1998) is an art historian, curator, art critic and consultant based in Athens. With a BA and MA from the Athens School of Fine Arts, his research and practice focus on hermetic symbolism, alchemical imagery and gothic narrative in the history of art, bridging theory with contemporary curatorial strategies.

Spyropoulos has curated numerous solo and group exhibitions in Athens, contributing to the contemporary art landscape with a critical and scholarly lens. He also collaborates regularly with cultural institutions and artists, offering strategic consulting and curatorial support.

His written work spans newspapers and art magazines in Greece, where he publishes articles on contemporary art criticism and theory. 

In 2024, Spyropoulos introduced the term Avant-Garde Hermeticism to articulate the visual language of artists such as Marcel Duchamp, Anselm Kiefer, and Raymond Douillet. This concept has been explored through his public lectures, published essays, and curatorial projects.
