Sharif Kamal Shahin, a diplomat with 27 years' experience and a former ambassador to Zambia, arrived in Iraq on Friday, the source said.
Egypt's foreign ministry spokesman has described the move as an "important step to promote relations between the two Arab countries."
Shahin's arrival in Baghdad comes just days after a visit to Egypt by Iraqi Foreign Minister Hoshyar Zebari.
Cairo has had no official diplomatic representative in Iraq since the July 2005 abduction and murder by Al-Qaeda of its diplomat Ihab al-Sharif in Baghdad.
In October 2008, Ahmed Abul Gheit made the first visit by an Egyptian foreign minister to Iraq in 18 years.
Egyptian oil companies have said they are studying infrastructure and refining operations in Iraq.
