Pompey Women will host LOSC Lille at the PMC Stadium on Sunday, August 4 (12pm kick-off) as part of their pre-season preparations.
The French side – who finished 11 in Division 1 Féminine last term – meet the reigning Hampshire and Portsmouth District FA Cup holders for a pre-season friendly.
Lille gained 18 points from 22 league games, but were condemned to relegation on the final day of the campaign.
They enjoyed a successful cup run in the Coupe de France, however, and went all the way to the final before losing 3-1 to European Champions Lyon.
Ticket news for the fixture will be announced in due course.
