The 59-year-old Australian said he was looking forward to coaching the Barbarians in their November 16 date with crowd-pleasing Fiji.
"It's a huge honour to be invited to coach the Barbarians," said Jones.
"The club perfectly embodies the values and traditions of the sport."
"I am looking forward to returning to Twickenham after a successful World Cup campaign to coach a Barbarians team containing some of the stars of the tournament."
Jones, who took over as England coach following the team's abject first round exit at the 2015 World Cup, is due to announce his final World Cup training squad on July 4 and the definitive 31-player squad in mid-August.
Jones is under contract until 2021, and although it was thought he would be under pressure if England fail to reach the last four, Rugby Football Union chief Bill Sweeney said he would like to retain Jones whatever happens in Japan.
