Her visit will take place on Tuesday, July 21, 2026, at the Royal Welsh Showground in Llanelwedd, Builth Wells.
Her Royal Highness is attending in her capacity as Patron of the Association of Show and Agricultural Organisations (ASAO), a role she has held since 2012.
Nicola Davies, chair of council at the Royal Welsh Agricultural Society, said: “We are honoured to welcome Her Royal Highness The Duchess of Edinburgh to the Royal Welsh Show.
“It is hugely encouraging that members of the Royal Family continue to take such an active and deep interest in rural matters.
“This will be an extremely special occasion for us.” “The Royal Welsh Show is about bringing people together, and Her Royal Highness will have the opportunity to meet some of the wonderful people who make the Royal Welsh so special.”
The Duchess, who last visited the Royal Welsh Winter Fair in 2018, will tour the showground and meet exhibitors, young farmers, and volunteers during her first visit to the Royal Welsh Show itself.
She is expected to see some of the new features planned for this year’s event.
The Duchess is well known for her support of farming, food production, and rural communities.
Richard Price, honorary show director, said: “The Duchess of Edinburgh is hugely knowledgeable about agricultural shows, having visited many events in her role as Patron of ASAO, so she is sure to keep us on our toes!
“We will be pulling out all the stops to show her the very best of Welsh agriculture and to ensure she leaves with very fond memories of the Royal Welsh Show and its people.”
The Royal Welsh Show will take place from Monday, July 20 to Thursday, July 23, 2026.
A highlight of the agricultural calendar, the four-day event features livestock and equine competitions, rural skills, food and drink, horticulture, forestry, countryside sports, shopping, and entertainment.
The event will bring together thousands of visitors, competitors, and industry professionals from across the UK and beyond.
Visitors can find full event details and ticket information on the Royal Welsh Agricultural Society’s website.
