U.S. National Science Foundation grants open now

197 open opportunities as of Oct 16, 2026.

Independent platform. Not affiliated with or endorsed by any government agency. Data from public federal sources.

This page lists every U.S. National Science Foundation funding opportunity in our database that is open for applications right now. U.S. National Science Foundation posts its grant and cooperative agreement notices on Grants.gov, and we copy the public details from there each day.

U.S. National Science Foundation is part of the U.S. National Science Foundation. Each listing below links to a summary page with the deadline, award range, eligible applicant types and the assistance listing number, plus a direct link to the official notice. The official notice is the only source that counts, so read it in full before you start an application.

Use the search box to narrow the list by keyword, or sort by deadline to see what closes first. If your organization is new to federal funding, plan for registration time: SAM.gov registration, a Unique Entity ID and a Grants.gov account can take several weeks to put in place.

Frequently asked questions

Where do I apply for U.S. National Science Foundation grants?

You apply through the official notice, usually on Grants.gov. Each opportunity page here links to that notice. GovGrantsUSA is an independent platform and does not accept applications on behalf of U.S. National Science Foundation.

Is GovGrantsUSA a government website?

No. GovGrantsUSA is an independent platform operated by VRLY Ventures LLC. It is not affiliated with or endorsed by any government agency. Opportunity details are summarized from public federal sources such as Grants.gov.

Does it cost anything to apply for a federal grant?

Searching for and applying to federal grants on Grants.gov is free. Be wary of anyone who asks for a fee to "release" a grant or guarantees an award.

How current is this information?

Listings are refreshed from public federal data every day, and each page shows when it was last updated. Agencies can change or cancel a notice at any time, so always confirm details in the official notice.

What do I need before I can apply?

Most applicants through Grants.gov need an active SAM.gov registration with a Unique Entity ID (UEI), a Login.gov account and a Grants.gov account linked to their organization. Registration can take several weeks, so start early.
