Gethin Jenkins (born 17 November 1980) is a Welsh former professional rugby union player who played as a prop for Pontypridd, Celtic Warriors, Cardiff Blues and Toulon.

Following some poor performances by Wales in 2020, he joined Wayne Pivac's backroom staff as the national team's defence coach.

After an impressive World Cup 2011, his signature was hotly sought after with Bath, Perpignan and Toulon all chasing a deal for the prop.

Jenkins became the ninth Welshman to win a Heineken Cup with Toulon when he played as a replacement in the final against Clermont Auvergne.

[6] In the 2005 Six Nations Championship he was rated one of the greatest influences in Wales' Grand Slam winning side, scoring a memorable try against Ireland.

In November 2007 Jenkins was asked to captain Wales against South Africa by Welsh temporary coach Nigel Davies.

[7] His reign as captain would last just one game as in December Wales hired Warren Gatland as coach who gave the captaincy to Ryan Jones.

[10] In June 2009 Jenkins, Adam Jones and Matthew Rees were selected as the British & Irish Lions front row for the second Test against South Africa.

Jenkins has also played rugby league, making regular appearances for Cardiff Demons in the late 1990s leading them to the 1998 Division Two Academy Grand Final.
