Darmian has become United's second summer buy after the £25 million arrival of Memphis Depay from PSV Eindhoven.
And he is set to be joined by a third newcomer after United and Bayern Munich agreed terms for the transfer of Germany captain Bastian Schweinsteiger.
United manager Louis van Gaal highlighted Darmian's versatility and attacking ability as reasons why he signed the former Palermo player.
"Matteo is a right-sided full back with the versatility of also being able to play on the left," the Dutchman told United's official website.
"He is a strong defender and has the ability to go forward in the attacking positions which is a fantastic attribute to have and much needed in the fast rhythm of the Premier League. Matteo will be a great addition to the team. I am delighted to welcome Matteo to the club and look forward to working with him in the coming days."
Darmian, who has won 13 caps for Italy and impressed in their 2014 World Cup campaign, said he was looking forward to playing for Van Gaal.
"It is a dream come true to be joining Manchester United," he stated. "I have loved the time that I have spent at Torino and I would like to thank the club and the fans for everything they have done for me.
"I am sure they can understand when the opportunity to join the biggest club in world came along it was something I had to do. To work with Louis van Gaal, a manager that has achieved so much in football is such an exciting prospect."
Darmian's arrival ends Van Gaal's long search for a right-back, where winger Antonio Valencia filled in for the majority of last season.
United had ruled themselves out of the running for Southampton's Nathaniel Clyne, who subsequently joined Liverpool, while Daniel Alves opted to sign a new contract with Barcelona.
Rafael da Silva, who has not started a league game since October, is now expected to leave Old Trafford with Galatasaray, Fiorentina and Napoli all reportedly interested in the Brazilian.
Darmian is expected to be part of the United squad who will travel to America on Monday for their pre-season tour.
They will face Club America, San Jose Earthquakes, Barcelona and Paris Saint-Germain and the Italian is likely to debut in the United States.
In announcing the 25-year-old's departure, Torino thanked Darmian for his four years of service with the Serie A club.
Thanks, @DarmianOfficial. We lived four wonderful years together. #SFT
