Support the Magic of the Mermaid Society

The Mermaid Society of Texas is a small but mighty nonprofit organization with a big mission — to celebrate and protect the soul of San Marcos through our unique blend of environmental advocacy, arts, and community spirit.

Every dollar you give is deeply valued and powerfully leveraged. At this time, 100% of our community programming and the beloved Mermaid Capital of Texas Fest is made possible through sponsorships tied to the festival. Your donation helps us bridge critical funding gaps, allowing us to continue providing meaningful programming, free community events, and creative environmental education initiatives throughout the year.

Our vision for the good work Mermaid Society can do is far and wide. From inspiring the next generation of eco-leaders to fostering a deep connection between our community and the San Marcos River, your donation helps us keep moving forward to reach our goals.

We’re proud to operate with below-average overhead and maintain transparency and trust by partnering with a local accounting firm for all financial management since 2016. Mermaid Society is a registered 501(c)(3) nonprofit, and your contribution is tax-deductible to the fullest extent of the law.

Your support keeps the river magic alive — thank you for believing in the power of community, creativity, and conservation.
