For 37 years, the Flagstaff Festival of Science has built a lasting legacy as a cornerstone of community engagement, education, and discovery in Northern Arizona. As the nation’s longest-running free science festival, it has reached generations of residents—sparking curiosity, expanding access to science, and strengthening connections between the public and the region’s rich network of scientists, educators, and institutions. Its sustained impact is reflected in a more scientifically engaged community, increased visibility of local research and environmental issues, and countless young people who first discovered their interest in STEM through Festival programs. By consistently removing barriers to participation and delivering high-quality, inspiring experiences year after year, the Festival has helped shape a culture where science is accessible, valued, and woven into the identity of the Flagstaff community.
