"We are delighted to announce this historic partnership between AS Roma and Qatar Airways, two great brands with global ambitions," AS Roma president Jim Pallotta said in a statement.
"With a new stadium due to begin construction late this year and the team in the Champions League semi-final for the first time for 34 years, it's an exciting time to be a Roma fan."
Qatar Airways will be the seventh shirt sponsor in Roma's 90-year history.
Launched in 1994, Qatar Airways bought a 49 percent stake in Italian carrier Meridiana last September, which was rebranded as Air Italy this year.
