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 Fourteenth Panhellenic Logic Symposium was hosted in Thessaloniki, under the auspices of the Aristotle University of Thessaloniki.

It was dedicated to the memory of Thanases Pheidas.
