Thailand is more than a tourist paradise. It is a regional hub for international development, environmental conservation, humanitarian aid, and social innovation. From the bustling migrant communities of Bangkok and Samut Sakhon to the vulnerable forest corridors of the Dawna-Tenasserim Landscape and the fragile marine ecosystems of the Andaman Coast, international NGOs are working tirelessly to address climate change, human trafficking, statelessness, and poverty.
But here is the challenge every NGO leader faces in 2026: Where is the money?
Government budgets are shifting. Traditional donors have new priorities. And the competition for grants is fiercer than ever.
That is why we created this guide.
In this complete 2026 directory, we list the most active International NGOs and Funding Agencies in Thailand
Whether you are a grassroots community-based organization (CBO), a mid-sized international NGO, or a research institution, this guide is your roadmap to sustainable funding in Thailand.
Let’s dive in.
