Hook hung up his boots after a 16-year playing career in May after making 149 appearances with his home region.
He also played club rugby for Perpignan and Gloucester and won 81 Test caps for Wales after making his debut in Argentina in 2006.
He won Six Nations Grand Slams in 2008 and 2012, a Championship title in 2013, and played at three Rugby World Cups. He also toured South Africa with the British & Irish Lions in 2009.
Now Hook wants to turn his attention to coaching.
“As I was coming towards the end of my career, particularly when I returned home to the Ospreys, I was helping out a lot with the young players and I really enjoyed it,” he said.
“I always remember Neil Jenkins taking me under his wing as a youngster and how important that was for me. The knowledge he passed on was invaluable and it’s something I want to be able to do as an aspiring coach.”
Hook will bring with him plenty of experience to the role. He currently sits in second place on the all-time Ospreys point scorer list with 841 points.
Hook already has coaching experience and qualifications under his belt after spending last season as attack coach for the Ospreys Under-18’s and assisting the younger kickers in the senior squad.
“I’m coming to the end of my level three in coaching which had to be put on hold due to the lockdown, but it’s pretty much done and obviously going to be a huge help going forward in my coaching career,” he said.
“People always associate the kickers being the outside-half or the fullback, but for me as a kicking coach it’s not just about those but the centres, the half-backs and the back three as well.
“It’s about working with all the back-line to make them better kickers. They’ll have to put the hard work in, but if I can pass my knowledge down to them to help the team improve then I’ve done my job.”
Ospreys rugby general manager Dan Griffiths said: “We are delighted to retain Hooky at the Ospreys.
“His achievements in the game and the experience he has acquired in both the international game, and on the domestic front in Wales, England and France gives him a wealth of knowledge to pass on to young players within the Ospreys pathway.
“In addition to his experience he is fantastic role model and a diligent professional who always invested time and effort in his preparation and in the young players around him.
“As with all our former players who have transitioned to staff, it’s about retaining individuals who add value, epitomise the character and commitment needed to drive the region forward, and can support Ospreys players to be the best they can be.
“I’m sure Hooky will be a great addition to the coaching staff and continue to inspire young players as he did in an Ospreys shirt.”
