Owens played 91 internationals for Wales and five Tests for the British and Irish Lions on two tours and spent his entire domestic career with the Scarlets where he made 274 appearances.
“Ken has had an incredible rugby career and been a brilliant ambassador for the game in Wales,” said Gatland. “I’ve enjoyed being able to coach him with Wales and the Lions.
“Ken is an incredibly passionate Welshman. I know it meant a lot to him to play for Wales and you could see that every single time he wore the red jersey. He was also very proud to represent Carmarthen Athletic and the Scarlets.
“Throughout his career Ken has been a dedicated professional and a great leader, always helping drive standards but also very popular with his teammates.
“He has been absolutely outstanding for Wales over the years and it was a very easy decision to name him as captain for the 2023 Guinness Six Nations, which turned out to be his final international campaign.
“Ken, his wife Carys, his family and friends can be immensely proud of all he has achieved.
“Diolch yn fawr iawn am bopeth Ken. All the best for the next chapter.”
