90. Internationale Messe Thessaloniki

The 90th Thessaloniki International Fair (ΔΕΘ) runs from 5 to 13 September 2026 at the Thessaloniki International Exhibition Centre. The fair marks 100 years since the first edition was held in 1926, making it one of Greece's oldest recurring trade and cultural events, and Japan is its honoured country for the first time in its history.

Alongside the trade-fair exhibits from Greek and international businesses, the event traditionally includes a public programme of talks, cultural events and pavilions from participating countries, and functions as a platform for political statements — Greek prime ministers have historically used their opening-day speech at the fair to set out economic policy for the year ahead.

Full programme details, exhibitor lists and opening hours are published by the fair's organisers ahead of the event.
