The Sheikh Omar Hadid Brigade (Arabic: لواء الشيخ عمر حديد, romanized: Liwāʾ ash-Shaykh ʿUmar Ḥadīd), also known as Islamic State in Gaza, was an Islamist militant group affiliated with the Islamic State in Iraq and the Levant that was reportedly active in the Gaza Strip around 2015. Its goals have consistently matched those of the Islamic State, in that it seeks to establish the al-Sham caliphate. As such, it opposes all forms of Palestinian nationalism while also supporting the elimination of all Jews and other "infidels" from the region.

The group's leader was unknown until Hamas Police raided the home of Yunis Hunnar on June 2, 2015, who was accused of leading the recently formed group and was shot dead while resisting arrest.

The group was named after Omar Hadid, an insurgent of Iraqi origin who was a member of Al-Qaeda in Iraq.
