World Metropolitan Day
Look beyond city boundaries
On 14 October, World Metropolitan Day provides a global forum that brings together metropolises from all over the world.
World Metropolitan Day 2026
Thinking, planning and acting at the metropolitan scale
World Metropolitan Day places the metropolitan perspective at the heart of the conversation on how increasingly interconnected urban areas are governed. In 2026, more than ever, stronger coordination and cooperation across institutions, sectors and territories are essential to shape effective, lasting policies for thriving metropolitan areas.
This day is a renewed opportunity for leaders around the world to advance governance models that are more collaborative, adaptive and fair, to respond to shared challenges beyond administrative boundaries.
