National Cannabis Festival 2027

The National Cannabis Festival is the East Coast’s flagship 4/20-weekend celebration, returning to the grounds of RFK Stadium in Washington, D.C. on April 17–18, 2027. Founded in 2015 around the push for cannabis legalization, it has grown from an advocacy rally into a full-scale festival of music, education, and community — while keeping its activist roots front and center. It’s a 21+ event.

Across the weekend, expect headline musical performances, policy and advocacy programming, a wide exhibitor village, and the festival’s signature mix of celebration and civic energy. As the anchor of the national 4/20 calendar, it’s the destination event for enthusiasts planning their spring around the holiday.

Plan ahead: lineups and tickets are typically announced in the months beforehand, and the D.C. date draws travelers from across the country — book early if you’re making a trip of it.
