Captain's Ball | Friday, Nov. 6, 2026, 5:30-9:30 P.M.

At the Dubuque County Historical Society and the National Mississippi River Museum & Aquarium, community is at the heart of everything we do. The Captain’s Ball is our largest annual fundraiser—and a celebration of the mission-driven work that makes our organization a vital resource for education, conservation, and access.

This year’s event will once again shine a spotlight on the impact of your generosity. The evening’s highlight, our Fund-the-Need appeal, supports the daily care and long-term wellbeing of the animals who call our campus home. Your gift provides essential resources that make it possible to:

• Enrich the lives of animals across campus through engaging, species appropriate experiences

• Sustain and enhance animal habitats to ensure safe, healthy environments

• Deliver critical veterinary care and ongoing wellness support

• Provide high-quality nutrition tailored to each animals needs

• Provide educational outreach to schools and underserved communities with our animal ambassadors

We invite you to be part of this unforgettable evening of connection, celebration, and purpose. your generosity makes these initiatives possible and sustains the care, education, and experiences that bring our mission to life.

Captain's Ball 2026: A Night in the Wild is presented by Riverview Companies.
