The 33-year-old utility player will join the Dragons next season and take the overseas quota space of the departing Ian Hindmarsh.
"This is an excellent signing for us," said Dragons coach Mick Potter.
"Jason is a real professional both on and off the field and he has shown this during his negotiations with the club."
Croker holds the Raiders records for most tries with 120 and appearances with 314.
Potter added: "He is an extremely consistent player who knows the rigours of hard rugby league week-in, week-out.
"His current coach Matthew Elliot rates him as being in the top three performers for the Raiders every week.
"He is a very determined person who wants to do his best every time he steps onto the field and I think he will be great for us."
