Mission and History

World Ocean Day rallies the world for collaborative, youth-led ocean and climate action on 8 June and throughout the year. We work in partnership with diverse youth leaders, youth-focused organizations, and others from all sectors in a growing global network to inspire and effectively engage the public, inform policymakers, and unite the world to protect and restore our blue planet.

On World Ocean Day, people everywhere can unite to celebrate and take action for our one ocean and one climate, which connect us all. Join together with your family and community, rally your company, and join with millions of others around our blue planet to create a better future.

By working together, we can protect and restore our shared ocean and create a stable climate. Join this growing global celebration in June and continue to grow the engagement year-round!
