Welcome to Vallejo Sister City Association & Vallejo Sister City Commission
How Are Sister Cities Formed?
A sister city, county, or state relationship is a broad-based, long-term partnership between two communities in two countries.

Get Involved
Thank you for considering getting involved with the Vallejo Sister City Association. Your support makes a significant difference in our ability to achieve our mission and positively impact our community. Here are a few ways you can get involved.
Visit Our Sister Cities
Vallejo proudly partners with seven sister cities worldwide. These relationships are long-term, community-based partnerships officially recognized when top officials from both cities sign an agreement. Each sister city organization operates independently, focusing on municipal, business, trade, educational, and cultural exchanges that benefit both communities.
Visit Our Friendship Cities
Vallejo proudly partners with six friendship cities worldwide. These relationships are less formal than our sister cities, and the first stage in establishing our relationship with communities abroad.
