The former Lille coach has signed a two year deal with the Italian club.
Roma have appointed their third boss in three years, former Lille coach Rudi Garcia, reports Goal.com.
Garcia met with senior club officials in New York to tie up the agreement and will begin a two year contract with the Serie A club.
The new coach was hand picked by Roma’s sporting director Walter Sabbatini, who was impressed with Garcia’s man management skills and commutative skills.
Garcia has spent five years as Lille boss, leading the club to a League and Cup double in 2011.
Roma had initially lined up former France boss Laurent Blanc but decided to go with Garcia after being impressed with him during interviews.
Other contenders for the post were Massimo Allegri of AC Milan and Walter Mazzarri.
Allegri decided to stay with AC Milan while Mazzarri left Napoli to join Inter Milan.
Club officials at Roma are under pressure to make the right appoint following several disastrous decisions regarding managers, with recent manager Zdenek Zeman proving to be a very unpopular choice.
One issue that Garcia will have sort out straight away is the future of club captain Daniele De Rossi.
The Italian has been strongly linked with a move to Chelsea following a disappointing season at Roma.
