The 2007 Yazidi communities bombings occurred on August 14, 2007, when four coordinated suicide car bomb attacks detonated in the Yazidi towns of Til Ezer (al-Qahtaniyah) and Siba Sheikh Khidir (al-Jazirah), in northern Iraq.

There were 796 people killed and at least 1,500 others wounded, making it the Iraq War's deadliest car bomb attack. It is also the fourth deadliest act of terrorism in history, after September 11 attacks in the United States, the Camp Speicher massacre in Iraq, and the Mai Kadra massacre in Ethiopia. No group claimed responsibility for the attack.
