Posidonia Exhibitions SA is a leading organiser of trade fairs in Greece, and operates through its headquarters located in Piraeus, Greece.

Posidonia Exhibitions SA has specialised in trade fairs regarding the international shipping and sea tourism industries. The company is the organiser of Posidonia, the international shipping exhibition, and the Posidonia Sea Tourism Forum, an international conference and exhibition about sea tourism. In 2023 the company launched the Posidonia Masterclass in Shipping, an online education platform that delivers a series of pre-recorded lectures about the maritime industry, providing a comprehensive overview of the unique and exciting world of shipping.

Posidonia, the international shipping exhibition, has long been established as one of the major calendar events of the shipping industry, and Posidonia 2024 attracted the most influential personalities from the Greek and international shipping community and major companies and organisations active in all sectors of the shipping industry. The international exhibition Posidonia first took place in 1969 and has been taking place every two years ever since.

Posidonia 2024 was the largest in terms of exhibition space and most publicised event in the exhibition’s history and has become the largest trade show in Greece. Posidonia 2024 welcomed 2,038 exhibiting companies from 81 countries & territories and was attended by 32,527 visitors from 130 countries. In total the exhibition was attended by 41,838 participants including exhibitors, visitors and media representatives. The exhibition had 23 national pavilions from the following countries and territories: Bahamas, Belize, Brazil, Cayman Islands, China, Cyprus, Denmark, Hong Kong SAR, Japan, Republic of Korea, Liberia, Malta, The Netherlands, Norway, Palau, Panama, Poland, Romania, Singapore, Sri Lanka, Turkey, United Kingdom, and the USA.

Posidonia not only serves as a bridge linking the international shipping industry with the Greek shipowners, who operate the largest fleet globally of over 5,000 vessels, the largest under the control of any national group, but also serves as the platform that brings international shipowners in touch with the latest developments in the shipping industry and offers them direct access to the entire range of shipping products and services available on the international shipping market. Posidonia 2026 will take place on 1-5 June 2026 in Athens, Greece.

The Greek Prime Minister traditionally inaugurates the exhibition, in the presence of Heads of State from major shipping nations, foreign Ministers, EU Commissioners, Secretary Generals of International Organisations, Chairmen of International Associations and Organisations and leading personalities of the world of shipping, trade and finance.

In 2006, Posidonia was for the first time awarded the US Trade Fair Certification, the only exhibition in Greece to receive this certification.

During Posidonia week, a number of networking sporting events take place including, the Posidonia Cup sailing race in Faliron Bay, Piraeus, the Posidonia Shipsoccer Tournament, a one-day 5×5 soccer tournament for the shipping industry, the Posidonia Golf Tournament, as well as the Posidonia Running Event in Piraeus. In 2022, a 3×3 Basketball tournament was added to the Posidonia sports events agenda.

Posidonia makes an essential contribution to the Greek economy every two years, with its thousands of visitors and exhibitors boosting the tourist industry and related sectors, as more than 10,000 people visit our country for the exhibition. Specifically, it is estimated that some €70 million are generated throughout Posidonia week by exhibitor and visitor spending on hotels, restaurants, business meetings, hospitality events, stand constructions, transportations, customs clearance and movement of exhibits etc. Moreover, such a high-quality event taking place in Athens promotes Greece and the city itself as an ideal destination for major international trade events, contributing to the future development of the MICE sector in the region, and also projecting a positive image of Greece to the world.

Posidonia is organised under the auspices of the Ministry of Maritime Affairs & Insular Policy, the Hellenic Chamber of Shipping, and the Union of Greek Shipowners, and with the support of the Municipality of Piraeus and the Greek Shipping Co-operation Committee.

The Posidonia Sea Tourism Forum, launched in 2011, has quickly established itself as a leading business platform for global cruising and yachting industry decision makers and governments, tourism bodies, regulators and ports and destinations from the entire Mediterranean. The biennial forum examines the need for new facilities, infrastructure and services as well as prospective joint ventures that are expected to result in important benefits for Greece as well as the countries in the wider Eastern Med region.

Top executives representing the most important international cruise and yachting companies participate, share their insight and know-how with the Forum’s audience and discuss business with exhibitors and participants. The event also enjoys the active support of CLIA Europe and MedCruise.

Since its inception, new focused workshops and seminars have been added to the Posidonia Sea Tourism Forum’s agenda, generating further growth. With approx. 1,000 participants and 35 exhibitors from over 20 countries and territories participating in this industry focused dialogue, the Posidonia Sea Tourism Forum has become the landmark event for the sea tourism industry in the Eastern Mediterranean.

In 2023, the Posidonia Sea Tourism Forum took place in Thessaloniki and the next edition is scheduled for 6-7 May 2025 in Heraklion, Crete.
