Ertuğrul Dursun Önkuzu (1 January 1948 - 23 November 1970) was a 22-year-old Turkish Idealist student from Zile, Tokat.

He was studying at the Ankara Technical Higher Male Teacher Training School when he was murdered by far-leftist students on 23 November 1970.

Some reports claim he was heavily tortured to death for 3 days including cutting his wrists, pumping air through his throat with a bicycle pump until his lungs burst and he was thrown from the window alive.

[14] After Önkuzu's murder, 3 left-wing students, Hikmet Parabakan, Abbas Balkır and Sinan Gündüz were kidnapped by idealists.

The three students were hung from the ceiling by their legs, their skin was cut with razor blades, their fingers were broken and Idealists left them in front of a hospital.
