Williams will compete in the women’s singles, according to a Wimbledon announcement on Tuesday.
The social media post showed her standing on a lawn in white sneakers.
Williams has not played competitively since injury forced her to retire from a first round match at Wimbledon last year.
The 23-time major champion last reached the Wimbledon final in 2019, losing to Simona Halep, who now teams up with Williams’ former coach Patrick Mouratoglou.
Williams will return to court in Eastbourne for the first time next week for the LTA’s Rothesay International, along with Tunisia’s world No. 4 Ons Jabeur for doubles, in what will be her first tournament appearance in nearly a year, according to the tournament.
Widely regarded as the GOAT of women’s tennis, 23-time Grand Slam champion Serena Williams says she is still striving to beat Margaret Court’s record of 24.
“I should have been about 30 or 32 (grand slam titles),” Williams told DailyExpertNews’s Christiane Amanpour earlier this year.
“I should have had it (the record), really, I’ve had a lot of opportunities to have it. But I’m not giving up.”
Williams had to miss January’s Australian Open on the advice of her medical team, when she announced in December that she was not “where I need to be physically to compete”.
Wimbledon is scheduled to take place from June 27 to July 10 at the All England Lawn Tennis & Croquet Club.
Jill Martin, Alicia Lloyd and Christiane Amanpour reported.
