In the announcement, it was confirmed that the christening is due to take place on Saturday 6 July in a small ceremony held in the Private Chapel at Windsor Castle.
"The godparents, in keeping with their wishes, will remain private," the statement read.
Speculation has been rife as to who will be named the godparents of Meghan and Prince Harry's son Archie Harrison, with contenders including media mogul Oprah Winfrey, fashion stylist Jessica Mulroney and Hollywood actor George Clooney.
"That would be a bad idea," the Ocean's 11 star responded. "I'm a father of twins and I can barely do that."
The royal baby's christening will be attended by around 25 people, the palace has confirmed.
Official pictures will be taken by photographer Chris Allerton, which will be shared by the duke and duchess following the ceremony.
Allerton famously photographed Meghan and Prince Harry's wedding last May.
In December, the Kensington Palace Instagram account shared a black-and-white photograph taken by Allerton of the royal couple at their wedding reception at Frogmore House.
On 19 May, the duke and duchess' official Instagram account shared a series of never-before-seen pictures captured by Allerton at the wedding, in celebration of their one-year anniversary.
The chosen location for Archie Harrison's christening is particular poignant for the royal couple.
Just over a year ago, Meghan and Prince Harry exchanged their vows in St George's Chapel in Windsor Castle.
Prince Harry was also christened at Windsor Castle, back in 1984.
