The CLIA - Cruise Lines International Association is the world's largest trade association for the cruise industry.

The "Cruise Portugal" brand brings together all Portuguese cruise ports that together promote the national cruise industry to the international sector. The ports of Leixões, Lisbon, Setúbal, Portimão, Azores, Madeira, and more recently, Figueira da Foz, participate annually in the major global events of the sector such as Seatrade Cruise Global, Seatrade Cruise Europe (Biennial), and Seatrade Cruise Med (Biennial).
