The centre-back was offered a new deal at the end of last season but he has now confirmed his departure and will become a free agent
The 27-year-old announced that he will be leaving in a social media post on Monday.
"The time has come to say goodbye to Chesterfield FC,” he wrote.
"Very disappointed in how things have ended but had some amazing moments at your club.
"You fans were some of the best I’ve ever experienced! Thank you for the way you embraced me - hope to see you all soon.”
The centre-back joined Chesterfield last November on a deal until the end of the season.
He made 11 appearances in total for the Blues, scoring once.
