Festival N°6 is an annual art and music festival held in and around Portmeirion, Wales. The festival presents a wide range of music genres across multiple stages. It is advertised as a family-friendly festival, and as such various areas of the festival are targeted to families, such as "No.6's Mischief Meadow" for children and a designated family camping area. In 2013 one of the organizers stated that due to the size of the village the festival was not likely to grow beyond 10,000 attendees across the weekend.
