The carmaker, which sells the brands Chrysler, Dodge and Jeep, said his appointment has been welcomed by the UK dealer council.
Goretti was formerly managing director of Chrysler Italy and most recently international project director of Chrysler LLC's global operation.
He has been brought in to manage the UK operation, third most important for Chrysler's sales worldwide, following the resignation of Simon Elliott, who is moving to Volkswagen Group to become director of Volkswagen Commercial Vehicles.
Mike Manley, Chrysler LLC executive vice president international sales, said: "His track record is outstanding. Adding someone as well respected as Federico underscores our commitment to the UK market."
The carmaker said Goretti brings to the organisation a broad range of international sales and marketing experience, having worked for a number of different auto manufacturers in Japan and the UK, as well as Italy.
"I’m confident Federico will enjoy good chemistry with our strong team of dealers and Chrysler employees," said Thomas Hausch, Chrysler LLC vice president - Europe, Middle East and Africa.
"We informed our dealer council ahead of this announcement and the reaction was very positive.
"They welcome his vast Chrysler background, substantial international sales and marketing experience - particularly in the UK - as well as his high standing with Chrysler headquarters as a result of his past successes.”
Goretti will report to director – international sales and marketing, western and central Europe, Jacques Bousquet.
Chrysler, Jeep and Dodge has avoided the decline in new car registrations in the UK market, with sales up year to date.
New vehicles in the group's line-up, such as the Jeep Patriot, have helped to grow the Company's position in this key market, which is the third-largest market for Chrysler LLC outside North America.
Globally, Chrysler has successfully negotiated the framework for a $30 billion refinancing in working capital.
The carmaker ended June with $11.7bn in cash and had first half earnings before interest, tax, depreciation and amortization of $1.1bn
