Hall has spent his entire career on Humberside apart from a five-game loan spell at Widnes where he played alongside Wakefield head coach, James Webster.
"I'm delighted to get Craig on board for 2015," said Webster. "Craig is a player that possesses great speed and we feel that his all-round game and versatility will add plenty to our current squad."
Hull KR chief executive Mike Smith said: "I'd like to thank Craig for everything he has done for the club over the past four seasons.
