The Duke and Duchess of Cambridge will christen their daughter Princess Charlotte during a private ceremony next month, Kensington Palace has announced.
Charlotte, who was born on May 2, will be christened on July 5 by the Archbishop of Canterbury, Justin Welby at St Mary Magdalene Church, Sandringham.
Kensington Palace said in a short statement: "Their Royal Highnesses the Duke and Duchess of Cambridge are pleased to announce the christening of Princess Charlotte will take place on Sunday, 5th July at St Mary Magdalene Church, Sandringham.
"Princess Charlotte will be christened by the Archbishop of Canterbury, the Most Reverend Justin Welby."
A few days after their baby was born, William and Kate announced she would be called Charlotte Elizabeth Diana - names that were a tribute to the Prince of Wales, the Queen and William's mother Diana, Princess of Wales.
The Archbishop has spoken of his joy at the forthcoming christening: " I am delighted to be invited to conduct the baptism of HRH Princess Charlotte. It will be an extraordinary honour and privilege to help welcome the Princess into the family of the church.
"Along with her parents and all her family, I look forward to joining in this joyful day of celebration and thanksgiving."
The Queen and Duke of Edinburgh are expected to attend the christening along with the Prince of Wales, who has become a grandfather for the second time, and the Duchess of Cornwall.
Kate's family - parents Carole and Michael Middleton and siblings Pippa and James - are likely to be invited, along with the godparents who have not been publicly named.
Bookmakers have already opened books on who the royal couple will pick as the godparents for their daughter, with William's cousins Princesses Beatrice and Eugenie the early favourites.
William Hill spokesman Rupert Adams said: "We think that William and Kate will decide to ask both Princess Eugenie and Princess Beatrice - and Pippa has a great chance of getting a call-up."
He added that betting suggested the couple may have six godparents: "They have got their work cut out trying not to disappoint a number of their friends. The good news for those who don't get the call is that we think they will not stop at two children."
The bookmakers have Beatrice and Eugenie as joint favourites, with odds of 1/5, followed by William's old school friend Hugh Van Cutsem 1/2 and Peter Phillips and Pippa Middelton, both evens, William's former nanny Tiggy Pettifer is 5/4, and the couple's close friends Sam Waley-Cohen and William Van Cutsem, both 6/4.
Jessica Bridge of Ladbrokes said: "No surprises that the early money indicates the couple will stick to their nearest and dearest. Punters are still hopeful that Pippa and Harry will be the stars of the show on July 5, not Charlotte."
Ladbrokes has Beatrice as 1/3 favourite followed by Eugenie 2/5, Peter Phillips 1/2, Hugh van Cutsem 4/6, and Harry and Pippa both evens.
St Mary Magdalene church, where Charlotte will be christened, is also where Eugenie was baptised.
It is walking distance from the Queen's private Sandringham home in Norfolk and close to the Cambridges' country house Anmer Hall.
It is used by the Queen when she is at residence at her Norfolk home and the Royal Family attend it on Christmas Day.
