İsmail Demiriz (born 1 April 1962) is a Turkish former football player, who played as a right-back, and manager.
In 2019, Demiriz was convicted in Turkey and sentenced to prison for over a half-dozen years for his affiliations with Hizmet, a self-described transnational association based on moral principles and outlawed in Turkey as allegedly an "armed terrorist group."[1]
Demiriz spent his whole career in Turkey and is best known for his stint with Galatasaray, for whom he played 251 times and scored seven times.[2] He helped Galatasaray win three Süper Lig titles, and ten other domestic titles. He was briefly a manager after retiring from football.
In September 2016, Demiriz was charged with being part of a Gülenist terrorist organization and detained in Istanbul.[3]
