Daley is set to become the first British diver to compete in five Games, having come out of retirement to compete in Tokyo three years ago.
An Olympian at the age of just 14 at Beijing 2008, Daley won gold alongside Matty Lee in Tokyo to add to three bronze medals he has achieved in individual and synchronised 10m events.
In Paris, he will seek to defend his title alongside team-mate Noah Williams.
“This Olympics is something I would consider to be a bonus Olympics,” said Daley, whose son, Robbie, convinced him to return.
“This Olympics has been about enjoying it, embracing every moment and taking everything in as much as I can. To be flagbearer too is just the icing on the cake.”
Glover, who has three children, bids for her third Olympic title after coming out of retirement for a second time – ending her career following both the Rio and Tokyo Games.
The three-time world champion, who will compete in Paris as part of the women’s four, became the first mother to row for Great Britain at an Olympics when she finished fourth alongside Polly Swann in the women’s pairs in Tokyo.
“I never thought I would be an Olympian. Being part of history as a flagbearer, I haven’t really got my head round it yet,” Glover said.
“Everyone I have told so far has cried, and I cried when I was told, which goes to show how much of an honour it is and how much it means.”
