The Duchess of Sussex will join Prince Harry at the Invictus Games in The Hague for the first few days, says a spokesperson for the couple.
The international competition will take place in The Hague, Netherlands, from 16 to 22 April after being delayed by the pandemic.
Team UK competitors said they would like to see Meghan, two-year-old Archie and nine-month-old Lili at the Games, with one competitor suggesting it would be a great way for Harry to show his loved ones what he has achieved.
Daniel O’Connor, who is from Hereford and suffers from chronic pain,, is competing in archery and indoor rowing this year.
He praised Meghan for her “continued support” at previous Invictus events.
The 31-year-old said: “I think everyone in the Games, all the competitors, are bringing friends and family, and I think if we have the right to bring friends and family then surely Prince Harry does.
“So she has shown a continued support of the Games. I think she’s doing a great job.

“I would love to see her at the Games. If she is, great, and I hope they bring the kids as well so they’ve got the whole family there.”
Meghan made her first appearance at an official engagement attended by Harry on September 24 2017 when she attended the Invictus Games opening ceremony in Toronto, Canada, although the pair sat about 18 seats apart.
The following day, the pair emerged hand in hand to make their first official public appearance together at the wheelchair tennis.
Harry and Meghan, who live in the US, did not attend the memorial service for the Duke of Edinburgh in London last month.
Harry is bringing a claim against the Home Office after being told he would no longer be given the same degree of personal protective security when visiting from the US, despite offering to pay for it himself.
The duke wants to bring his children to visit from the US, but he and his family are “unable to return to his home” because it is too dangerous, his legal representative has said.
Team UK will compete in nine sports at the Invictus Games: athletics, archery, wheelchair basketball, cycling, powerlifting, indoor rowing, wheelchair rugby, swimming and sitting volleyball.
Harry played an instrumental role in bringing the Games to the UK in 2014 when 300 competitors from 13 countries took part in the inaugural competition in London.
A trip to the Warrior Games in Colorado a year earlier had been the inspiration, as Harry saw first hand how sport helped inspire recovery and support rehabilitation of wounded troops.
