Akram, 24, penned a three-year contract with Steve McClaren's side, joining from Gharafa where he won the Qatar Stars League this term.
"This is a dream come true, to play in Europe. FC Twente is a good club with a big coach," Akram told Twente's official site.
"I want to develop further at FC Twente and grow together with the club."
Experience
Former England manager McClaren, who led Twente to the Dutch Cup final this season, welcomed his new signing in Enschede.
"We've been following Nashat for a year. He's a young and very talented player, who has bags of experience given his age," he said.
Akram, who won over 70 caps for Iraq, had a successful trial at Manchester City last season but the deal fell through after he failed to acquire a work permit.
He is expected to join his new club after the FIFA Confederations Cup in South Africa next month.
