The Thessaloniki International Fair, abbreviated TIF (ΔΕΘ), is an annual international exhibition event held in Thessaloniki, Greece's second-largest city. It has been held in the first week of September since 1926, and its opening is traditionally marked by a series of programmatical statements by the Prime Minister of Greece. The 2020 fair was cancelled due to the COVID-19 pandemic, the first cancellation since WW2.
