The 24 year-old has penned a multi-year deal.
Jack Regan's move to The Ospreys has been officially announced.
The Birr man makes the jump from The Highlanders in New Zealand to the Welsh region.
We documented the 24 year-old's journey to this point in his career last month, which you can read here.
It's a three year deal and speaking to the club website Regan had this to say:
“This is a great opportunity for me with the Ospreys and a team with such a proud history.
“There was interest from other clubs but the squad there is building impressive performances and wins, and you just feel is heading for success.
“I just want to be a part of that and play my role and add some value to the squad. I cannot wait to get to Swansea and to get going.

“This a real chance to play at the top level and learn from the quality locks, like Alun Wyn Jones, Adam Beard and Bradley Davies, at the Ospreys.
“I have watched a lot of the Ospreys games and you can see Toby is giving young players a chance, and for a young guy, that’s very exciting. He trusts all the young lads to do a job for the team, you cannot ask for more than that from a coach.
“This is just a great opportunity for me to develop as a player after my experiences with Ulster and the Highlanders.”
