TLDR
Prince William was filmed singing the Welsh national anthem in Welsh at a Six Nations match in Cardiff, a small but emotionally loaded moment that thrilled royal supporters and underscored his long-running effort to embody his Welsh title.
Royal Voice in Welsh Red
In a crowded Principality Stadium in Cardiff, the Prince of Wales did not just stand for the Welsh national anthem. Cameras caught him singing along in Welsh, every line of “Hen Wlad Fy Nhadau” clear on his lips as the crowd roared around him.

According to Daily Mail, the clip came from Wales’s Six Nations clash with Italy, where William, patron of the Welsh Rugby Union, watched from the stands. The stakes on the pitch were high. Wales ended a bruising losing run with a 31-17 win, and fans online were quick to say the prince had “brought good luck with him”.
On X, one admirer wrote that “every note William sings carries the heart of Wales”, while another admitted that “Prince William singing the Welsh anthem confidently always surprises me”. Others simply called his vocals “fantastic” and loved seeing their future king so visibly invested in Welsh rugby.
The moment played out like a tiny homecoming scene, a future monarch wrapped in a red scarf, singing in a language he did not grow up speaking, but that now defines one of his most symbolic titles.
What the Anthem Moment Reveals
William’s fluency in the anthem is not an overnight transformation. He and Catherine became the Prince and Princess of Wales after Queen Elizabeth II’s death, and since then, they have worked to show that the role is more than a historic nameplate.
Daily Mail notes that William has previously spoken of a “deep affection” for Wales and even turned to language app Duolingo to brush up on Welsh. Years earlier, he remarked that “when the Welsh national anthem goes, you know you are home”, a line that now lands differently when people see him mouthing every word in the stadium.
Social media reactions to the new clip reflect that shift. One fan posted that “the Welsh love him and the Princess of Wales”, while another said the video “made me tear up” because it was “lovely to see such pride and emotion for their National Anthem”. For a prince whose title has not always sat easily in Welsh politics, visible effort counts.
St David’s Day greetings, filmed entirely in Welsh, daffodils pinned to their lapels, and now an anthem sung with conviction. Each gesture builds a picture of a couple determined to root their royal story in the country they represent.
Rugby as Family Language
Rugby is the thread that runs through much of that story. William’s long association with the Welsh Rugby Union is mirrored by Catherine’s patronages in English rugby, turning the sport into a shared stage for their public life.
Behind the palace gates, it doubles as a family pastime. Catherine has spoken about all three children throwing themselves into the game. Prince George and Prince Louis are said to play at school, while Princess Charlotte joins in when the family turns the garden into a makeshift pitch.
In a conversation with members of England’s World Cup-winning women’s team, Catherine laughed that she does not want to be tackled by George anymore. She has also revealed that Louis takes part in “Rugbytots” sessions, early coaching that leaves him, in her words, really enjoying the sport.
When William stands in a red scarf, singing alongside thousands of Welsh supporters, he is not only a patron performing his duty. He is a father raising the next generation on the same game, and a future king quietly auditioning for long-term acceptance in a nation whose anthem he now knows by heart.
Do moments like William singing the Welsh anthem make you feel differently about the modern royal role in Wales, or do you see them as simply part of the job?
