Devrimci Karargâh (English: Revolutionary Headquarters) was a nominally Marxist-Leninist organization in Turkey.

[citation needed] DK first came to public attention in April 2009, when some of its members were involved in a six-hour gun battle with police in the Istanbul neighbourhood of Bostancı, leading to the death of a policeman, a bystander, and the organization's leader Orhan Yılmazkaya.

Journalist Aylin Duruoglu was detained for over six months for knowing one of DK's alleged members.

[4] Former police chief Hanefi Avcı, an Islamist-leaning conservative, is also accused[5][6] and was charged in the Odatv case of the Ergenekon trials.

In February 2017 Devrimci Karargâh announced it was dissolving and becoming part of the Revolutionary Communard Party, the main organisation composing the United Freedom Forces.
