Daley was left out of the 18-strong team named by Team England on Tuesday, which includes his Tokyo synchro team-mate Matty Lee, and fellow Olympic gold medallist Jack Laugher.
Daley wrote on his Instagram feed: “I won’t be competing at this year’s Commonwealth Games in Birmingham.
“Before the Olympics last year, my coach and I decided I would take a year out from the sport to have some time to rest and be with my family.
“Can’t wait to watch all my teammates kick some butt this summer!”
Lee, who won 10m synchro gold with Daley in the Japanese capital, made his Commonwealth Games debut on the Gold Coast four years ago but finished out of the medals.
Lee said: “I enjoy the Commonwealth Games because it’s something different and it has a special place in my heart because I always wanted to go to a Commonwealth Games.
“I feel like I can do really well, and I think doing it for England, we always want it to ‘come home’, and I want to be the one to ‘Bring It Home’.”
The team also includes Olympic medallist Dan Goodfellow and former Commonwealth Games medallists Lois Toulson, Noah Williams and Matthew Dixon.
