Sepehr Heydari (Persian: سپهر حیدری, born 19 June 1980 in Esfahan, Iran) is a retired Iranian football defender.
He scored the most important goal of his career in the 96th minute against Sepahan on the final day of the season which won the league for Persepolis after six years.
During the 2008/09 season he was once again put in the starting line up by Afshin Ghotbi but when Ghotbi resigned and Peyrovani took over, Heidari was replaced and played as substitute for some time before being put back in the starting eleven for the AFC Champions League by new coach Nelo Vingada.
He won the Hazfi Cup in 2011 with Persepolis but after the managerial changes the new coach Hamid Estili announced that he does not need Sepehr and he may leave the club.
He was invited to Team Melli by Afshin Ghotbi in January 2010 and played against Mali.
