Wales men and women will face the Barbarians in a double-header at Allianz Stadium in Twickenham in June.
The men’s match will kick off at 14:00 BST on Saturday, 27 June before the women’s game follows at 17:00.
The matches are expected to be uncapped fixtures.
It is considered an away game for Wales so Barbarians choose the venue as the “home side”, while the Principality Stadium is hosting non-related rugby events over the summer with Metallica playing a rock concert in Cardiff on Sunday, 28 June.
Wales men last played the Barbarians in November 2023 in Cardiff when the hosts won 49-26 in an 11-try uncapped encounter.
It was a final farewell to Welsh legends Alun Wyn Jones and Justin Tipuric, who both played for the Barbarians, and full-back Leigh Halfpenny, who started for Wales.
Wales were coached by Warren Gatland against a Barbarians side led by Eddie Jones and Scott Robertson.
