Moors joined the Tigers ahead of the 2015 season and has become a key member of Daryl Powell’s pack.
"Junior Moors is a high-quality player who has continued to get better during his time at the club,” said Castleford head coach Powell.
“His ability as a ball player in the middle of the field is outstanding, as is his ball-carrying strength."
The 31-year-old has been sidelined for the last eight weeks with a knee injury but could return next week as Castleford look to secure the League Leaders’ Shield.
After agreeing a one-year extension to his previous deal, Moors said: "I'm over the moon. I've really enjoyed my time here.
"We have a great bunch of blokes here at Castleford and great coaching staff so it was a really easy decision to make."
