The singer joins Florence + The Machine, Robbie Williams, Bob Dylan and Neil Young in topping the Hyde Park event in London.
The Canadian, 50, is best known for her 1997 hit My Heart Will Go On which was the theme to James Cameron's blockbuster film, Titanic.
The Grammy-award winning artist said: "It's my first time doing a show in beautiful Hyde Park. I'm so excited.
"I love London, and it's a great honour for me to be part of the Barclaycard presents BST Hyde Park concerts. I can't wait. Summertime in London, here we come!"
She will perform on July 5 with support acts yet to be announced. The performance will come a month after she closes her second Las Vegas residency at the famous Caesars Palace hotel.
Dion forged her reputation with records like The Power Of Love and Because You Loved Me. More recently her Las Vegas residency A New Day... became the highest-grossing concert residency ever, taking roughly £300 million.
James King, senior vice president of AEG Presents, said: "Celine's record-breaking career has seen her perform her many iconic songs on the globe's most iconic stages, yet never before in Hyde Park.
"It is therefore with the utmost excitement that we are bringing Celine Dion to Hyde Park for her only European show of 2019."
Daniel Mathieson, head of experiential marketing and partnerships for Barclaycard, said: "We are incredibly proud to be hosting such a huge icon this year.
"Celine is one of the most celebrated and respected musicians of all time and it will be a privilege to have her perform alongside what is shaping up to be a fantastic set of headliners.
"We are looking forward to seeing her bring some of her biggest hits to Hyde Park and it remains to be seen whether there will be a dry eye in the house after such a titanic performance."
Previous acts to have played British Summer Time include Stevie Wonder, Taylor Swift, The Rolling Stones, The Strokes and Black Sabbath.
Tickets for the show will be available in a fan pre-sale on January 23, with general sale tickets available on January 29.
