2025 Seaweed Saturday Long - Vibrant Green

April 26, 2025 | Portland, ME

A free, one-day expo of seaweed food, art, and fun on the Portland waterfront!

Join us Saturday, April 26th, from 11am to 4pm for Seaweed Saturday at the Gulf of Maine Research Institute. Get ready for a can't miss seaweed celebration with friends, family, and farmers! Free, for all ages.

At Seaweed Saturday expect interactive demos and activities featuring dozens of local seaweed farms, businesses, and organizations. Maine Sea Grant will offer hands-on seaweed identification workshops and local artists will exhibit their seaweed-inspired works. In the marketplace, seaweed farms and businesses will showcase their seaweed products to taste or take home. Here, you'll find everything from seaweed soaps to pre-prepared kelp pizza crust.

NEW this year, we'll also have 4 expert panel discussions on seaweed farming, history, science, and product development in GMRI's beautiful Cohen Center. The panels are free to attend but space is limited. Online registrations for each panel will be coming soon!
