The 33-year-old Frenchwoman made the announcement via a Twitter post yesterday.
"Hi, guys. I have something to tell you: I am coming back. ... It's going to be a huge challenge," Bartoli said in a video she put on Twitter.
"I have still a lot of practice ahead of me, but I am hoping to be ready for March and the Miami Open."
Bartoli mentioned three events she is particularly looking forward to: the French Open, the Fed Cup and, of course, Wimbledon.

She hit two-fisted shots for forehands and backhands, just like her idol, Monica Seles.
Bartoli was coached by her father, a doctor, and they came up with other unique elements.
She would cross her arms before serving, never bouncing the ball before a toss. She would stand well inside the baseline to receive an opponent's serve. And she would hop in place or take practice swings between points.
Then came the magical two-week run to the championship there six years later. Bartoli never dropped a set and capped her fortnight with a 6-1, 6-4 victory over Sabine Lisicki in the final, closing the match with an ace.
A year later, Bartoli became the first woman in 17 years who declined to try to defend her Wimbledon title.
At a news conference before the 2014 tournament, Bartoli tugged at the collar of her white top to reveal strips of blue tape providing support for her right shoulder and explained: "Literally, I can't even lift my arm every morning."
She since moved on to other pursuits, including TV commentary, launching a shoe line and designing jewelry.
