Apply to be a 2026 Vendor!

Thank you for your interest in Big Day of Play! We’re excited to officially open vendor applications for our 2026 event. Big Day of Play brings thousands of community members together for a day of recreation, connection, and fun, and we’re looking for vendors who want to be part of this incredible experience. Whether you’re sharing resources, promoting your organization, or offering interactive activities, we invite you to apply and join us in creating an unforgettable day for the Seattle community.

Spots are limited and fill quickly, so we encourage vendors to apply early to secure their place at the event.

Questions? Feel free to contact the Big Day of Play Planning Committee via email at bigdayofplay@seattle.gov.

We’re beyond grateful for the overwhelming support and can’t wait to build an even bigger and better event in 2026!
