Harrison spent the last campaign at Elland Road, playing 46 games in the Championship as they finished 1st and secured promotion back to the Premier League after a 16-year absence.
He will now continue his development at Leeds for another season under the guidance of Marcelo Bielsa.
Harrison joined City in January 2018 after enjoying a fine period at our sister club New York City, which enhanced his reputation as one of the most exciting young prospects in the United States.
Operating from a wide position, he found the back of the net 14 times in 59 appearances during his two seasons at the Yankee Stadium.
Everyone at City would like to wish Jack the best ahead of the 2020-21 season.
