Johann van Graan will take over as head coach of Munster in November after signing a two-and-a-half year contract with the province.
Van Graan joins from his role as South Africa forwards coach, where he played a key role in developing the forwards and attack for the 2015 Rugby World Cup.
In 2009 and 2010 he secured Super Rugby honours with the Bulls, as forwards and attack coach.
Van Graan said: "I am immensely excited and honoured to join Munster and to be part of a Club with a unique ethos and history dating back 138 years to 1879.
"Some of the words I associate with Munster Rugby are passion, excellence, ambition and integrity, and I feel very fortunate to be handed this opportunity.
"I am looking forward to working with the Munster players, support staff and supporters on this new journey, and to become part of their community."
The appointment means a restructuring of the coaching ticket at Munster, with van Graan taking on the same responsibilities as Rassie Erasmus.
He will work at first alongside Erasmus, subject to work permits, which the province hopes will be attained by mid-November to ensure a seamless transition.
"In Johann we are getting a recognised rugby intellectual with a proven track record"- Garrett Fitzgerald
Munster chief executive officer Garrett Fitzgerald said their work to appoint a new head of coaching was thorough: "After a worldwide search we are delighted to secure Johann van Graan as Munster Head Coach.
"Rugby was the focal point of this process and in Johann we are getting a recognised rugby intellectual with a proven track record and extensive experience working with a national side.
"An analyst of the game, his technical ability and interpersonal skills have made him an integral member of the South African rugby landscape for over a decade, and it is now time for an ambitious Johann to make an impact in a new rugby environment.
"We know Johann, with forwards coach Jerry Flannery and backline and attack coach, Felix Jones, will continue to establish the structures and processes required to bring this Munster team forward in terms of growth and success."
IRFU Performance Director David Nucifora added: "Johann is an exciting addition to our coaching team and we are delighted to welcome him to Irish rugby. His track record with the Springboks and the Bulls, in Super Rugby, is impressive and we are confident he will use this experience, and more, to continue the progress in Munster rugby."
