The Derna Protection Force (DPF; Arabic: قوة حماية درنة),[6] also known as the Derna Security Force,[2] was a Libyan militia formed by Ateyah Al-Shaari on 11 May 2018, during the Libyan National Army (LNA) assault on Derna.

[2] The militia was founded on 11 May 2018 by Ateyah Al-Shaari, the leader of the Shura Council of Mujahideen in Derna.

Despite these clashes, it had been commented in October 2018 that after "losing fighters, leadership and control of the city", the DPF had effectively "ceased to exist as an organization".

[5] The LNA blamed 2 improvised explosive devices attacks in Derna on 2 June 2019 on the DPF, despite the group being defunct.

On the following day, the attack was claimed by the Islamic State of Iraq and the Levant.
