Founded in 2003, the Nantucket Shellfish Association is a 501(c)(3) nonprofit organization dedicated to protecting Nantucket's harbors, water quality, and shellfisheries.

For more than two decades, NSA has supported research, education, scholarships, grants, and community partnerships that strengthen the future of our island's shellfisheries and the waters they depend on.

Beginning in 2024, NSA expanded its impact by launching new youth education programs, harbor health initiatives, scholarships, grants, and community events that connect residents, students, businesses, boaters, homeowners, and seasonal visitors with the beauty, history, and importance of Nantucket's shellfish and harbors.

We welcome members, donors, business partners, volunteers, and collaborators who share our commitment to protecting Nantucket's harbors, preserving our shellfisheries, and ensuring future generations can enjoy these extraordinary natural resources.
