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.
