Mahmoud has been unattached since parting ways with Saudi Arabian club Al Ahli in December 2013, yet he has still been selected by head coach Radhi Shenaishil for the tournament in Australia.
The 31-year-old was the player of the competition in 2007 when Iraq lifted the trophy, scoring four goals including the winner in the 1-0 final victory over Saudi Arabia.
And he is in contention to lead the line again for Iraq as they bid to regain the title after being knocked out in the quarter-finals in 2011.
Swindon Town midfielder Yaser Kasim is also included in the squad along with Columbus Crew forward Justin Meram.
Shenaishil's youthful group contains two teenagers, with 18-year-old Humam Tariq and 19-year-old Mahdi Kamil both given the chance to shine.
Iraq have been drawn in Group D alongside holders Japan, Jordan and Palestine. They start their quest for the crown against Jordan in Brisbane on January 12.
