About Seattle Sister Cities

Seattle is proud to be a leader in promoting and developing sister city relationships with 21 international communities. Our program has a strong 60 year history of connecting Seattlites to the world and shaping Seattle's global image. Each of our 21 sister cities is organized by a separate sister city association, which is a 501(c)(3). Each nonprofit organizes programs, activities, and cultural exchanges with local Seattle members and friends around the world. Together the sister cities organize an annual reception to celebrate the culture of each sister city, their programs, and foster relationships within Seattle's international community.
