The 28-year-old French No1, ranked seventh in the world, said she was taking the decision with immediate effect because of persistent injuries at a news conference following a defeat by Simona Halep at the Western and Southern Open in Cincinnati.
“It’s time for me to retire and to call it a career,” Bartoli said. “I feel it’s time for me to walk away.”
“My body was really starting to fall apart and I was able to keep it together, go through the pain – with a lot of pain – throughout this Wimbledon and make it happen.
“I have pain everywhere after 45 minutes or an hour of play. I’ve been doing this for so long. Body-wise, I can’t do it any more.”
She added: “It’s never easy… but that was actually the last match of my career. I just can’t do it anymore.”
Bartoli thrashed Sabine Lisicki 6-1 6-4 to win her maiden Grand Slam title at SW19 back in July.
“That was probably the last little bit of something that was left inside me,” she said. “It’s been a tough decision to take. I’ve been a tennis player for a long time and I had the chance to make my biggest dream a reality.
“You know, everyone will remember my Wimbledon title. No-one will remember the last match I played here.
“I made my dream a reality and it will stay forever with me, but now my body just can’t cope with everything.”
