One Ocean Week Seattle is a region-wide, international gathering of ocean leaders, innovators, researchers, startups, policymakers, artists, educators, and communities to accelerate solutions for a sustainable, inclusive maritime future.

Hosted by Maritime Blue, the week features summits, cultural events, community activities, youth and workforce development programming, and global delegations – all with the aim of catalyzing the Blue Economy while leading on climate action, ecosystem health, and equity.

We invite you to participate by hosting an event during the week! Partner-led events are at the heart of the event—bringing together diverse voices, showcasing real work, and driving meaningful conversations that extend beyond the event itself.
