St Helens RLFC have announced the appointment of Nathan Brown, who will join the Saints at the end of the season on a three-year deal.
The Super League side will welcome the new head coach after he completes his final year with the Huddersfield Giants.
Saints chairman Eamonn McManus told the club's official website: "We are extremely pleased that Nathan will be joining us next season. I believe he is ideally suited for the Saints both with regard to the way we want to play and as to what we aim to achieve in terms of success.
"He is still a relatively young coach but already has pedigree and experience gained over many years as a head coach at the highest levels both in the NRL and in Super League."
Brown added: "It's an honour to be appointed the head coach of St.Helens. They are a great and historic club and continuously associated with success; I'm relishing the challenge for next season onwards.
"They have a strong first-team squad and more promising youngsters coming through their system, along with a great new stadium and training facility."
The 38-year-old has had experience coaching in the NRL with St George Illawarra.
