About the Event

Convening Leaders for Ocean Innovation, Collaboration, & Action

Every October, Seattle becomes the world’s meeting point for the Blue Economy. One Ocean Week Seattle brings together ocean leaders, innovators, investors, policymakers, artists, and communities from around the globe for seven days of summits, showcases, and celebrations all in service of one goal: a sustainable, inclusive maritime future.

In 2025: 50+ events · 1,200+ registrants · 15 countries represented

Hosted by Maritime Blue, the week combines high-level policy dialogue with hands-on innovation, cultural programming, and youth engagement — because solving for the ocean takes collaboration.

This event is endorsed by the United Nations Decade of Ocean Science for Sustainable Development as a Decade Activity. Use of the United Nations Decade of Ocean Science for Sustainable Development logo by a non-UN entity does not imply the endorsement of the United Nations of such entity, its products or services, or of its planned activities.
