Smotherman, 33, signed from Iserlohn Roosters of Germany’s DEL, and scored the overtime winner in the Challenge Cup final win over Guildford Flames in his first season.
Giants coach Adam Keefe said: “Jordan is a player we had been tracking for a while and it was great to have him hit the ground running in 2018/19 to contribute to the Elite League and Challenge Cup success.”
“He is big forward who will bring offence and work ethic to our 2019/20 team. I know our fans loved hearing about the lengths Jordan went to in order to be in Belfast for his debut and I know they will love watching him in teal again this season.”
Smotherman has also represented Sweden, as well as playing in Denmark and the ECHL.
