Williams will compete in ladies’ singles, according to an announcement from Wimbledon Tuesday.
The social media post showed her standing on a grass court with white sneakers on.
Williams has not played competitively since an injury forced her to retire in a first-round match at Wimbledon last year.
The 23-time major champion last reached the Wimbledon final in 2019 where she lost to Simona Halep, who now works with Williams’ former coach Patrick Mouratoglou.
Williams will first make her return to the court in Eastbourne next week for the LTA’s Rothesay International, pairing up with Tunisia’s world No. 4 Ons Jabeur for the doubles event, in what will be her first tournament appearance in almost a year, according to the tournament.
Widely considered to be the GOAT of women’s tennis, 23-time grand slam champion Serena Williams says she’s still aiming to beat Margaret Court’s record of 24.
“I should have been at like 30 or 32 (grand slam singles titles),” Williams told CNN’s Christiane Amanpour earlier this year.
“I should have had it (the record), really, I’ve had many opportunities to have it. But I’m not giving up.”
Williams was forced to miss January’s Australian Open following the advice of her medical team, announcing in December that she wasn’t “where I need to be physically to compete.”
Wimbledon is scheduled for June 27 to July 10 at the All England Lawn Tennis & Croquet Club.
