Bartoli and Murray will join Ross Hutchins and another female player at the Queen's Club, which hosts one of three Rally For Bally mixed doubles fundraising matches that day. The others will feature Anne Keothavong, Tim Henman, Martina Navratilova and Jamie Murray at the Aegon Classic in Birmingham, and Petra Kvitova, Greg Rusedski, Agnieszka Radwanska and Jonathan Marray at the Aegon International in Eastbourne.
The Rally For Bally is part of a national fundraising effort being held in memory of former British No.1 Elena Baltacha, who died of liver cancer on May 4.
"Bally was my friend and I want to do everything I can to help the Rally For Bally," Bartoli said. "She was a lovely person and she always wanted to help other people, so everybody coming together like this is a really great tribute to her.
"I'm looking forward to being back on a grass court again, especially with Andy. I'm sure it will bring back lots of good memories of Wimbledon for both of us."
The Rally For Bally, via the Just Giving page, has already raised almost £45,000 in text and online donations. All money raised will be split between the Royal Marsden Cancer Charity, which successfully treated Hutchins last year, and the Elena Baltacha Academy of Tennis.
Donations can be made here, or text "EBAL60 £10" to 70070, to make, for example, a £10 donation via your mobile phone. Any finals day tickets purchased for the Aegon Championships between now and the event will see an additional £10 charged and donated to the fund.
