Prince William and Catherine, both 42, took to their official Instagram account on Thursday (local time) to share the sweet card, which features an informal picture of the royal couple with their three children - Prince George, 11, Princess Charlotte, 9, and Prince Louis, 6 - in the countryside.
They captioned the post: “Wishing everyone a very happy Christmas.”
The card simply reads: “Wishing you a very Happy Christmas and New Year.”
The photo is not a new one, but is from the family’s summer holiday, first shared by Kate in September when she revealed she’d finished cancer treatment.
The couple were absent from King Charles and Queen Camilla’s pre-Christmas luncheon at Buckingham Palace on Thursday, as they are already in Norfolk at their Amner Hall home for a festive break.
Catherine, who underwent a course of chemotherapy and was declared cancer-free, spoke about her health struggles at Westminster Abbey on December 6.
Speaking to Paloma Faith, one of performers at the event, she shared: “I didn’t know this year was going to be the year that I’ve just had.
“But I think lots of people this year have had such challenging times, many who are here today.”
The event will air on Christmas Eve on British TV channel ITV.
Catherine recently revealed her focus is to “stay cancer-free” after finishing her treatment.
The royal - who has been married to Prince William since 2011 - admitted it had been an “incredibly tough” period for herself and her family.
She said on X: “As the summer comes to an end, I cannot tell you what a relief it is to have finally completed my chemotherapy treatment. The last nine months have been incredibly tough for us as a family. Life as you know it can change in an instant and we have had to find a way to navigate the stormy waters and road unknown.”
The princess also described her cancer journey as “complex, scary and unpredictable”.
The card included a rare photo of the couple with their children, Archie and Lilibet.
Archie, 5, and Lillibet, 3, have largely been kept out of the spotlight and are rarely seen in photos.
The Sussexes chose to share a selection of highlights from their year on the holiday card, including Harry and Meghan on their four-day tour of Colombia in August and the family-of-four on a walk.
