The Armenia international, 30, joins the club from Premier League side Arsenal until 30 June 2020, for a fixed fee of €3 million.
The agreement also includes potential additional payments that could reach a maximum of €100,000 – depending on the meeting of certain performance targets.
“It’s a great opportunity for me to begin a new chapter, with a great club,” said Mkhitaryan.
“I know what this club is all about and I am sure we can achieve great things together.”
Mkhitaryan joins the club after amassing a wealth of European experience, having previously represented the likes of Manchester United, Borussia Dortmund and Shakhtar Donetsk.
“Henrikh fits our desire to add players to the squad who can serve as examples to our younger players, and who have the technical quality to quickly adjust to Serie A football,” said Roma sporting director Gianluca Petrachi.
Mkhitaryan will wear the No. 77 with the Giallorossi.
