The 35-year-old, who won two premierships with the Melbourne Storm and then another last season with the Sydney Roosters, will hang up his boots at the end of the current campaign.
Cronk's retirement comes 16 years after he first pulled on a Storm jersey and, in the years since, only Johnathan Thurston has received as many plaudits as one of the NRL's very best playmakers.
Through 360 NRL games, 22 Origins and 38 Tests for Australia, Cronk has won it all.
