St George Illawarra have confirmed Anthony Griffin will remain head coach for a further season, until at least the end of the Dragons' 2023 campaign.
The club took up the option in Griffin's contract earlier this week, extending his tenure for a third season.
"I am very appreciative to extend my time as head coach of the Dragons," Griffin said.
"We are heading in the right direction, and myself and all the great people at the club are determined to play our roles in bringing future success to the Dragons.
"I have thoroughly enjoyed my time so far and I'm excited by what's to come this season and beyond.
"The challenge of a new year starts this weekend in our first trial against Parramatta, and my immediate focus remains on a strong preparation for the upcoming season."
Dragons chief executive Ryan Webb said Griffin's influence on all aspects of the organisation was a key factor to his retention.
"The club has undertaken a lot of change in the last 18 months and Anthony has played a positive role, both on and off the field," Webb said.
"The board and I feel Anthony is the right man to continue setting the required standards to return the Dragons back to where they belong."
Griffin's extension will see his NRL coaching career reach its tenth season in 2023, following stints with the Brisbane Broncos (2011-14) and Penrith Panthers (2016-18).
The 55-year-old will coach his 200th NRL game in the Dragons' Round 3 local derby clash against the Cronulla-Sutherland Sharks.
