Celebrated on 09/19/2026
National Cleanup Day, observed annually on the third Saturday of September, began in 2017 as a grassroots effort to encourage community-led environmental stewardship. It has since grown into a nationwide movement, with over 1 million volunteers participating in 2023 alone.
National Cleanup Day was founded in 2017 by Steve Jewett and Bill Will, two environmental activists who recognized the need for a dedicated day to mobilize communities for large-scale cleanups. The first event saw participation from thousands of volunteers across the United States, focusing on parks, beaches, and urban areas. The day was established in partnership with organizations like Keep America Beautiful and the Earth Day Network to amplify its impact.
Since its inception, National Cleanup Day has expanded rapidly, with events now held in all 50 states and coordinated through a central website that allows volunteers to find local cleanups. The day has also incorporated digital tools, such as the Cleanup App, which tracks waste collected and provides data for environmental research. Modern celebrations often include educational components, teaching participants about recycling and waste reduction. The event has inspired similar initiatives globally, such as World Cleanup Day, which takes place on the same day.
