The meeting will address "the growing presence in Iraq and Syria of extremists, notably the Islamic State (IS)," the ministry said in a statement.
It added that the rise of IS meant the "search for a political solution to the Syria crisis was needed more than ever".
Since declaring a "caliphate" in June, IS has conducted a lightning offensive, taking control of territory straddling Iraq and Syria.
The jihadists sparked worldwide horror and condemnation this week when they released a video showing the beheading of US journalist James Foley.
Saudi foreign ministry spokesman Osama Nugali told AFP that a "meeting between some Arab states will be held tomorrow (Sunday) to discuss some Arab issues," without elaborating.
