World record holder Brigid Kosgei will defend her London Marathon title in April.
The 25-year-old Kenyan broke Paula Radcliffe's 16-year-old marathon world record in October by winning the Chicago Marathon in a time of 2:14:04.
Kosgei's record-breaking run came six months after she triumphed at the London Marathon for the first time.
"I am very much looking forward to returning to the London Marathon," she told the event's official website.
"Last year was an incredible year for me and it started by winning in London. Coming back will be very special and I hope it can be the start of another memorable year."
The race will be held on Sunday, 26 April.
Kosgei will be joined in the elite women's field by 2018 champion Vivian Cheruiyot, three-time Berlin Marathon winner Gladys Cherono, 2019 Valencia Marathon champion Roza Dereje, and current world champion Ruth Chepngetich.
Spencer Barden, head of elite athletes at the London Marathon, said: "Paula Radcliffe's world record had stood for so long and was one of the great markers in modern athletics so for Brigid to beat it and beat it so comprehensively was incredible.
"It is a mouth-watering prospect to see what she can do on her return to the London Marathon."
The elite men's field will be announced on Tuesday.
