The French star won the title in two straight sets, beating compatriot Gael Monfils, 7-5, 6-3, in front of an enthusiastic crowd at the Khalifa International Tennis and Squash Complex.
Qatar Airways, Official Airline of the six-day event, has been a strong supporter of the tournament over the years.
The tournament saw former World Number 1 crowd favourites Roger Federer and Rafael Nadal compete, but they failed to make it to the final.
Qatar Airways Chief Executive Officer Akbar Al Baker said: “My congratulations go out to Jo-Wilfried Tsonga for winning this year’s tournament. The Qatar ExxonMobil Open gets better year after year and we were very proud to have flown some of the world’s best tennis players to Doha for what was an exciting tournament.”
Tsonga will now compete in next week’s Australian Open in Melbourne, his sixth time playing in the prestigious competition since turning professional in 2004.
