King Charles III celebrated Father’s Day as he remains estranged from Prince Harry.

The monarch, 76, marked the holiday on Sunday with throwback photos shared to his and his wife Queen Camilla’s joint Instagram account.

The initial photo displayed a black-and-white shot of Charles’ father, Prince Philip, as he pushed a young Charles and his sister, Princess Anne, on a wooden swing.

In the second photo, Camilla, 77, posed with her dad Bruce Shand at her wedding to Charles in 2005.

“To all Dads everywhere, we wish you a happy Father’s Day today,” the caption of the post read.

Charles made no mention of sons Harry, 40, or Prince William in the tribute.

William, 42, was honored on Father’s Day by his and Kate Middleton’s three children on the Prince and Princess of Wales’ Instagram account.

The homage showcased two photographs of William with his children: Prince George, 11, Prince Louis, 7, and Princess Charlotte, 10. The second picture captured the kids playfully lying on top of their father.

“Happy Father’s Day, Papa (before and after!) We love you! G, C & L 💖,” the message to William read.

Charles, who received a cancer diagnosis last year, and William are both in a strained relationship with Harry, who stepped down from his royal responsibilities with his wife, Meghan Markle, in 2020 and relocated to the United States.

The Duke and Duchess of Sussex currently live in a $14 million mansion in Montecito, Calif. with their kids Prince Archie, 6, and Princess Lilibet, 4.

Last month, Harry said that his father “won’t speak” to him in his explosive BBC interview after the duke lost his appeal to maintain tax-payer funded security detail in the UK.

“There have been so many disagreements between myself and some of my family,” Harry admitted in the May 2 interview.

“Some members of my family will never forgive me for writing a book,” Harry also said, referring to his 2023 memoir “Spare,” adding, “Of course, they will never forgive me for lots of things.”

Harry also said in the interview: “I don’t know how much longer my father has.”

Charles responded by not inviting Harry and Meghan, 43, to his annual Trooping the Colour event on Saturday for the third year in a row.

Meanwhile, Charles, Camilla, William, Kate and their kids showed a united front on the Buckingham Palace balcony to mark the king’s official birthday.
