The Tiffany & Co. Foundation seeks to preserve the world’s most treasured seascapes and landscapes, directing funding to make strategic and meaningful impact in ocean conservation.
The Tiffany & Co Foundation’s recent grantmaking centers on ocean conservation, with large awards used to expand marine protected areas, protect coral reefs, and support related coastal and high-seas initiatives. One of its clearest funding signals is repeated support for Oceans 5 through Rockefeller Philanthropy Advisors Inc, including $1,000,000 grants in both 2023 and 2025 to advance marine protected areas. Another major thread is reef protection: the foundation gave Wildlife Conservation Society $565,000 in 2023 for Reefs for the Future, which works to protect resilient reefs. It also funds field and policy work at scale, including $300,000 in 2025 to Conservation International Foundation for conservation initiatives across the high seas, Mexico, Peru, Costa Rica, the Galapagos Islands, Japan, and Niue. The foundation’s portfolio also includes responsible mining and mine reclamation, showing that its conservation work extends beyond marine ecosystems to land-based restoration tied to environmental harm. Across these grants, the foundation backs organizations that combine on-the-ground implementation, research, advocacy, and community capacity building.
Marine protected areas are a recurring priority. In 2025, the foundation gave $300,000 to Wildlife Conservation Society to create, expand, and scale the management of marine protected areas in Kenya, the Philippines, Solomon Islands, and Belize. It also supported the Coral Reefs of the High Seas Coalition with $100,000 in 2025 to create the first coral reef marine protected areas of the high seas. Coral reef work appears in several forms. In 2023, Great Barrier Reef Foundation USA Inc received $150,000 for coral propagation to protect large-scale areas of the Great Barrier Reef from bleaching, and Woods Hole Oceanographic Institution received $100,000 for research on environmental change and disease impacts on reef health. The foundation also funded sustainable tourism with $150,000 to Coral Reef Alliance for practices that protect coastal communities and reefs in high-tourism areas of the Caribbean.
Typical grant size is mid-six figures: the 25th percentile is $100,000, the median is $150,000, and the 75th percentile is $391,250. The recent list shows both one-time awards and repeat support to the same organizations across multiple years, including Rockefeller Philanthropy Advisors Inc, Wildlife Conservation Society, Conservation International Foundation, Great Barrier Reef Foundation USA Inc, Resolve Inc, and Oceana Inc. The foundation operates as a grantmaker rather than an individual funder, and it does not make program-related investments. One active program accepts unsolicited Letters of Inquiry, while other ocean-conservation grants are limited to U.S.-based 501(c)(3) organizations.
