The suspensions come after authorities accused the operations of inciting sectarian violence, Voice of America reported.
Baghdad is currently seeking to curb rising unrest that began with violence at a Sunni protest camp last week. At least 170 people have been killed since the fighting began Tuesday.
A statement Sunday from the Communications and Media Commission accuses the networks of encouraging revenge against the security forces who are trying to stop the violence.
Al-Jazeera said in a statement it is astonished by the decision and it covers all sides of Iraqi news stories.
The decision does not block the networks' satellite signals but warns of legal actions if the networks deploy reporters inside the country, VOA said.
