The toll comes as the country grapples with months of protests among the Sunni Arab minority, tensions in a swathe of territory in northern Iraq disputed by the Kurds, and a protracted political deadlock that has blocked key legislation.
The violence showed no signs of letting up today as new attacks, including a suicide bombing, killed 19 people.
The UN mission in Iraq said a total of 761 people were killed across the country in June, bringing the overall death toll for the past three months to 2,518. Most of those killed in June were civilians and a further 1,771 were wounded as a result of violence.
Attacks in June targeted a wide cross-section of Iraqi society -- government targets and security forces were hit by car bombs, mosques were struck by suicide attackers, anti-Qaeda militiamen were shot dead, and Iraqis watching and playing football were killed by blasts.

The surge in violence comes amid a protracted political standoff within Iraq's national unity government, with little in the way of landmark legislation passed since a 2010 parliamentary election.
Meanwhile, tensions have persisted in a swathe of territory in northern Iraq that Kurdish leaders want to incorporate into their autonomous three-province region over Baghdad's objections.
At the same time, violence has shown no sign of slowing.
Today, eight former Sunni tribal militiamen were kidnapped from their homes north of Baghdad in pre-dawn raids by gunmen wearing military uniforms before being shot dead, assassination-style.
The men were all former fighters in the Sahwa, a collection of Sunni tribal militias that turned against Al-Qaeda and sided with the US military from late 2006 onwards, helping turn the tide of Iraq's bloody insurgency.
No group immediately claimed responsibility for today's violence, but Sunni militants linked to Al-Qaeda frequently target the Sahwa, whom they regard as traitors, and Shiite Muslims, whom they see as apostates.
