The mosque, named Hamou al-Qadu, was bulldozed to the ground, a local official in the Iraqi province of Nineveh said, Al-Alam TV network reported.
The historic religious building dated back to 1880 C.E., the era of Ottoman Empire.
Last month, the terrorist group blew up the oldest mosque in the Iraqi province of al-Anbar.
Another mosque in Mosul was demolished in January.
ISIL (also known as ISIS and IS), controls swathes of land in Syria and Iraq.
The Takfiri group started its campaign of terror in Iraq in early June 2014. The heavily-armed militants took control of Mosul before sweeping through parts of the country’s Sunni Arab heartland.
The terror group has been carrying out horrific acts of violence including public decapitations and crucifixions against all communities such as Shias, Sunnis, Kurds and Christians.
