The Constantine Andreou Archive is a family-led online resource devoted to the Brazilian-born Greek artist Constantine Andreou (1917–2007).

The website has an illustrated artwork catalogue, a documented biography, an exhibition chronology and a developing bibliography. The catalogue begins with works in the family collection. Each entry has a stable Archive identifier, and records are expanded as documentation is checked. Uncertain information is identified explicitly.

The website offers English, Greek, French and Brazilian Portuguese versions.

The Archive is an ongoing research project. Art historians, curators, librarians and others with relevant information are invited to contact the Archive. Corrections supported by verifiable sources are welcome.
