"Mr Ahmadinejad will attend next week's Persian Gulf Cooperation Council in Doha on an official invitation," Mojtaba Samareh Hashemi told state broadcasting.
"This is the first time that the Islamic Republic of Iran has been invited to the summit," he added.
Heads of state from Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates are due to discuss the violence in Iraq and escalation of the Iran nuclear crisis at the December 3-4 summit.
The six oil-rich Gulf Cooperation Council (GCC) leaders will focus on "Gulf security" at their meeting in Doha, secretary general Abdulrahman al-Attiyah said earlier this month.
Samareh Hashemi did not specify in what capacity Iran had been invited but said that the aim of Ahmadinejad's presence was to boost ties with Arabian peninsula states.
"The aim of this trip is boosting ties between Iran and the regional nations, especially in the Persian Gulf area," he said. "The participation of the president shows that the will of both sides to consolidate cooperation is greater."
