St. Louis Earth Day Festival

Come celebrate Earth Day April 26-27, 2025 from 11am - 5pm both days at earthday365's annual St. Louis Earth Day Festival in Forest Park! Our theme this year is Climate Hope, and we will have a special focus on vendors, sponsors, and educational resources that inspire and empower solutions to climate challenges. Whether you are coming for the food, the music, or the activities, we promise you will leave more inspired about real progress being made to heal our people and our planet, more connected to those around you, and more knowledgeable about how you can take action in your daily life! The St. Louis Earth Day Festival is a community tradition to learn about sustainable practices, organizations, products, and services. Along with our 200 vendors, our Main Stage will host a Sustainable Fashion Show, local music and performers, and we will honor and celebrate local leaders with our Environmental Awards Ceremony. Meet local area non-profits and businesses that share Earth Day values. We will be showcasing entertainment and Green Dining Alliance restaurants. earthday365 Members will receive extra perks - stay tuned for more exciting festival details!
