About marine grants

Marine grants fund ocean and coastal conservation, habitat restoration, fisheries, and resilience projects. NOAA Fisheries is a primary federal funder through programs like its Coastal and Marine Habitat Restoration and community-based restoration grants, frequently partnering with the National Fish and Wildlife Foundation (NFWF) on coastal resilience. Nonprofits, tribes, universities, and coastal governments are typical applicants.

A long list is the starting point, not the shortlist. Our grant prospecting guide shows how to narrow marine grants down to the funders most likely to say yes, using their giving records.

What grants are available for marine and coastal projects?

Funding supports coastal and marine habitat restoration, living shorelines, coral reef and fish passage work, and coastal resilience. NOAA Fisheries administers habitat restoration and resilience grant programs, and the National Coastal Resilience Fund, run with NFWF, supports community projects across coastal states and territories. Larger restoration awards can require substantial scope and matching contributions.

Does NOAA fund marine conservation?

Yes. NOAA Fisheries funds coastal and marine habitat restoration, community-based restoration, and large transformational restoration and resilience efforts. It also partners with the National Fish and Wildlife Foundation on the National Coastal Resilience Fund. Eligible applicants generally include nonprofits, tribes, academic institutions, and governments.

Who else funds marine nonprofits?

The National Fish and Wildlife Foundation co-funds major coastal resilience efforts with NOAA, and private funders such as the Walton Family Foundation support fisheries innovation. State coastal programs, Sea Grant, and ocean-focused private foundations provide additional avenues. Coastal projects often combine federal grants with private match to reach their full budgets.
