The Panhellenic Logic Symposium is a biennial scientific event that was established in 1997. It aims to promote interaction and cross-fertilization among different areas of logic. Originally conceived as a way of bringing together the many logicians of Hellenic descent throughout the world, the PLS has evolved into an international forum for the communication of state-of-the-art advances in logic. The symposium is open to researchers worldwide who work in logic broadly conceived.

The Eleventh Panhellenic Logic Symposium will be hosted in Delphi, organized by the National and Kapodistrian University of Athens and the National Technical University of Athens. The University of Cyprus will help in the organization. The scientific program of the symposium will consist of hour-long invited talks, tutorials and presentations of accepted contributed papers and posters.
