Wales will host Fiji, Australia and South Africa during the Autumn Nations Series in November, rugby chiefs announced on Monday.
Fiji will provide Wales's opening opposition at the Principality Stadium on November 10, followed by the Wallabies seven days later, then the world champion Springboks on November 23.
Wales, who beat Fiji and Australia at the World Cup in France last year, face South Africa at Twickenham on June 22 before two away tests against Joe Schmidt's Wallabies in early July.
WRU executive director of rugby Nigel Walker said: "This is an exciting Autumn Nations Series schedule for Wales, with fixtures against three key southern hemisphere opposition teams in quick succession.
"We look forward to welcoming Fiji, Australia and South Africa to the Principality Stadium this November as we celebrate the stadium's 25th anniversary."
