“Obviously a lot of people have been wondering where I’m going to go to post Rio and, with some reflection, I’ve decided that I’m actually going to retire,” she told Weekend Today on Channel Nine.
She had hinted at a major announcement on Twitter earlier on Sunday.
Meares represented Australia at four Olympics and is Australia’s most decorated cyclist at the Games.
Meares won gold in the 500m time trial and bronze in the sprint in Athens in 2004.
After breaking her neck in a crash in January 2008, she won sprint silver at Beijing’s 2008 Olympics just seven months later.
She won her first sprint gold medal at the London Olympics in 2012, defeating British rival Victoria Pendleton.
On Sunday, she revealed she needed several pain-killing injections in her spine to compete at the Games in Rio.
“Having looked back and seen all the things that I have achieved and assessed some of the injuries that I have had to manage going into Rio,” Meares said.
“Most people were unaware just to get to Rio I had six cortisone injections through my spine.
“Having had to change tack for six months leading into it and to achieve the things I have, I feel satisfied and happy to step aside from the sport and try something new and different.”
After the Rio Olympics the 11-time world champion had said she intended to take some time to catch her breath and spend time with her family before coming to a decision about her future.
“I didn’t get a fairy tale ending [to these Olympic Games] but I had a good ending,” she said.
