Lynn, who also oversees all aspects of the women’s rugby programme at Hartpury College and University set-up, will take charge of Wales for the first time during the Six Nations.
He already coaches a large contingent of Welsh internationals at Gloucester-Hartpury, with captain Hannah Jones, prop Sisilia Tuipulotu, fly-half Lleucu George and hooker Kelsey Jones among them.
Gloucester-Hartpury currently hold a three-point lead in the Premiership ahead of Harlequins and a 10-point advantage on Bristol Bears in fifth, with the top four teams qualifying for the play-offs.
Since the start of December they have won their past six league games – including against three of their four top four rivals. They place Leicester Tigers away in their next game on Saturday.
“It’s something we set out in June, July, let’s get a home semi-final, it’s knock-out rugby, it’s what we enjoy, and my full focus is on Gloucester-Hartpury and making sure we can [do that],” Lynn added.
“We said in the meeting on Monday, where we’ve come from just before Christmas, playing all those top four teams and coming away with max points it’s incredible.
“I’m super proud of the group of players and staff that we’ve got. That job has been done and now it’s looking to build going into knockout stages.”
