Thalassa Foundation is a Geneva-based marine conservation funder focused on protecting Mediterranean biodiversity, with a strong emphasis on Greece and the Greek islands. It supports project-based work that combines habitat protection, marine research, environmental education, awareness campaigns, and local capacity building, often by partnering with NGOs, municipalities, universities, and conservation networks. Its portfolio suggests a collaborative, place-based approach to ocean and coastal stewardship rather than broad general grantmaking.
Project-support grants with an application/submission process; funding appears to be partnership-oriented and likely targeted at specific initiatives in Greece and the Mediterranean, including co-funded or in-kind supported projects rather than unrestricted support.
Submit a project proposal through their 'Submit a Project' process and clearly align it to marine biodiversity, habitat conservation, research, education, capacity building, or awareness raising in Greece or the Mediterranean. Proposals are likely strongest when they include local partners, measurable conservation outcomes, and a clear connection to marine ecosystems or island communities.
