2026 UN General Assembly Philanthropic Side-Events

As foundations and philanthropic leaders prepare for the 81st Session of the United Nations General Assembly (UNGA), we've put together this calendar of side events, with registration links included throughout.

We're excited to join the conversations at UNGA 81 and Climate Week NYC 2026, engaging with foundations and philanthropic leaders who are driving innovative solutions and building partnerships to address today's most pressing global challenges.

UNGA events have blue (■) titles; Climate Week events have green (■) titles.

Hosting a side event? If it's philanthropy-focused, we'd love to include it. Send the event details to victoria.mendez@cof.org, and we'll add it to the calendar and help promote it.
