Cardiff Blues prop Gethin Jenkins will captain Wales in their one-off Test with South Africa on 24 November.
Jenkins will become the 125th captain of Wales
The 26-year-old takes over from World Cup skipper Gareth Thomas to become the 125th man to wear the Wales armband.
"Anyone who knows Gethin will tell you he sets high standards for himself and those around him," said Wales caretaker coach Nigel Davies.
Jenkins is Wales' most-capped prop with 52 appearances, but he is being kept out of the Blues side by John Yapp.
The match will be caretaker boss Davies' only game in charge before new Wales coach Warren Gatland takes over in December.
"This came as a bit of a surprise and I took some time to think about it, but there was only ever going to be one answer," said the Pontypridd-born Jenkins, who made his international debut against Romania in 2002 and won three Test caps on the 2005 Lions tour.
"I just try to be the best team player I can be, it's a huge honour and just to think of the players that have gone before me is pretty awe-inspiring in itself.
"I've been in the Wales squad for five years and have played with some great players and some truly inspirational captains, but if I can achieve anything near what Gareth Thomas has achieved in terms of his role as a leader then I'll be a happy man.
"If I can emulate his calmness under pressure and his ability to consistently raise standards or his leadership qualities and knack of diffusing difficult situations on the pitch, then I'll be doing a pretty good job.
"It's South Africa's first game since winning the Cup, so the scalps aren't going to come much bigger than that for at least the next four years.
"As a team we are all feeling the disappointment of our World Cup exit and I can't think of any better way to ease the pain than to take it out on the Springboks."
