It has also been confirmed that Mossy Lawler has signed an extension to his contract that will keep him at Munster until 2028 as assistant coach.
The attack and back-line coaching responsibilities for the Munster senior Men's squad will be shared by Jared Payne and Lawler.
The new appointment completes the Munster Men's coaching team for next season, following last week's announcement of Jimmy Duffy as their new forwards coach.
A 20-cap Ireland international, Payne retired from playing in 2018 at the age of 32 due to injury.
He immediately transitioned into coaching and was defence coach at Ulster between 2018 and 2022, before moving to Top 14 club Clermont Auvergne for the 2022/23 season.
The New Zealand native has spent the past three years with the Scarlets in Llanelli, initially joining as backs and attack coach before later overseeing the defence programme.
He enjoyed an illustrious playing career that saw him line out for the Chiefs, the Crusaders, and the Blues in Super Rugby. He moved to Ireland in 2011.
The 40-year-old played for Ulster for seven years and made his Ireland debut against South Africa in November 2014. He toured New Zealand with the British & Irish Lions in 2017.
Commenting on his move back to Ireland, Payne said: "I'm incredibly grateful for the opportunity to be joining Munster Rugby.
"Munster is a club with a proud history, strong values, and a special connection with its supporters and community. As a family, we're excited to become part of that.
"There is a huge amount of ambition across the club and I'm looking forward to working alongside the players and staff to help move the club forward.
"There is a lot to be excited about, and I can't wait to get started."
Munster head coach Clayton McMillan stated: "Jared brings wide-ranging skills, having played and coached extensively in Ireland for 11 years as well as experiences in New Zealand, France, and Wales.
"Over this time, he has coached both sides of the ball and developed an excellent reputation for empowering players and assisting them to fulfil their potential. I look forward to Jared and his family joining the club.
"I'm equally delighted that Mossy has extended his contract. The attack portfolio is vast, and I have always had the view that it is a two-person job.
"There is accountability to bring a higher level of detail to their respective areas of responsibility within our attack framework, and I believe that in Mossy and Jared, we have two innovative and detailed coaches who will work outstandingly well together."
The province's General Manager, Ian Costello, added: "Jared is a highly respected coach that we believe will be an excellent fit to work closely with Mossy, and completes a very exciting and ambitious coaching team for next season."
