Ianna Andreadis (Greek: Γιάννα Ανδρεάδη; born 1960, Athens) is a Greek-origin artist and photographer who has created many books, published in France and Mexico, as well as international projects with worldwide participation.
In 2004, she coordinated a digital photo project called The World Around a Flame/Olympic Truce 2004 that was exhibited in Athens during the Olympic Games that year.
Later (1989–90) she studied pre-history in the Institute of Art and Archaeology and joined excavations and surveys in Vallée des Merveilles in the south of France.
Travelling to Zimbabwe, Malawi, Namibia, South Africa in 1993-94, she also created a new series of landscapes, and worked on a number of lithographic limited edition albums, with Franck Bordas.
She has also worked on a long-term photo-project for a book, that involves photographing—at regular intervals—stages in the construction of the Quai Branly Museum designed by Jean Nouvel.
