The terms of the 31-year-old’s transfer will remain undisclosed.
Doidge joined the Hibees in the summer of 2019 from Forest Green Rovers and became a hit with the supporters over the last four and a half years.
The striker bagged 19 goals in all competitions during his first season with the Club and 13 the year after before injuries hampered his game-time.
During his time at Easter Road, Doidge went on to make 148 appearances and score 43 goals.
He will now re-join Forest Green, and everyone at Hibs wishes him all the best for the future.
Hibernian FC Head Coach Nick Montgomery added: “I would like to thank Chris for his efforts this season and his time at the Club. It has been a difficult season for him with a few injuries and lack of game time, but he has always been a model professional.
“The opportunity for Chris to take a long-term contract back at a club he knows incredibly well was one we all agreed would be in the best interests for both parties.
“With Adam Le Fondre and Martin Boyle coming back into the squad, alongside the arrivals of Emiliano Marcondes and Myziane Maolida, we have options and good squad depth up-front going into the second half of the season.”
