Suffolk Day is observed in the ceremonial county of Suffolk, England, every June 21. Established in 2016 by Mark Murphy of BBC Radio Suffolk, the day celebrates the rich history, culture, art, and landscapes of the county. The date was chosen as it marks the longest day of the year, rather than being historically significant. Various events are organized across Suffolk, including treasure hunts, guided tours, concerts, food tastings, and charity events, engaging local communities and visitors alike. Suffolk is known for its notable towns such as Ipswich, Bury St Edmunds, and Felixstowe, and is recognized as a center for British horse racing and cultural festivals, including the Aldeburgh Festival of Music and the Arts. Stakeholders involved in the celebration include Suffolk County Council, the University of Suffolk, and Ipswich City Council.
