March for the Ocean (M4O)

March for the Ocean is not just a protest. It's also a celebration of the fact that it’s not too late to turn the tide to protect and help restore what we love

This summer we will see a new blue wave of resistance – and celebration - for the other 71 percent of our environment that is the Ocean.

The Ocean is Rising and So Are We!


The Blue Frontier Campaign and 70+ partners are mobilizing a broad and diverse constituency to #MarchForTheOcean to demand ocean solutions for the problems that threaten our blue planet. A growing chorus of supporters including environmentalists, scientists, surfers, divers, celebrities, fishermen, social justice advocates, small businesses, major aquariums, deep-sea explorers, students, parents, teachers and citizen activists - everyone who gets so much from the ocean, lakes and rivers - is mobilizing to give something back.


On Saturday, June 9, 2018, join the March for the Ocean in Washington D.C. or join one of many simultaneous marches, flotillas, and water celebrations across the country!

Contribute to building this blue wave. Celebrate and protect all that our waters - salty, brackish and fresh - provide us. Join the hundreds of organizations, and notable advocates who will March for The Ocean June 9!

For those of you marching, march back down the route to clean up. We hope everyone will reduce, reuse, and recycle but sometimes trash makes its way to the ground. Help us ensure March for the Ocean prevents plastics and garbage from entering our waterways and ocean!

On Saturday June 9, 2018, World Oceans Day weekend and the beginning of the 2018 hurricane season, the March for the Ocean (M4O) campaign will mount mass marches, flotillas and rallies in our nation’s capital and around the country. People will be mobilizing to stop reckless offshore oil drilling being pursued by the Trump administration and to promote job-generating clean energy, to call for large-scale reduction in plastic waste that is killing ocean wildlife and to promote protection and restoration of our coastlines in the face of rising seas and intensified hurricanes like last year’s Harvey, Irma and Maria.
