Redshaw came off the bench to bag a brace for the Shrimps in Saturday's 4-1 win at York, moving the former Manchester City youngster to 10 goals for the season.
Manager Jim Bentley told his club's official website: "We have been keen to sign Jack again for some time and I am delighted that he has agreed to join us for another year.
"He is a great lad and a great player and will continue to develop with us over the next 12 months."
