The Qatar Open, known as the Qatar ExxonMobil Open, is a professional tennis ATP 500 tournament played on outdoor hardcourts. It is held annually in January at the Khalifa International Tennis and Squash Complex in Doha, Qatar, since 1993. It was part of the ATP Tour 250 series on the ATP Tour. In 2025, the tournament was upgraded to an ATP 500-level event.
The Qatar Open has been the site of the ceremonial opening of the ATP World Tour season since 2009. That year saw Rafael Nadal and Roger Federer (then-World No. 1 and 2, respectively) kick off the season on a tennis court situated on a boat off Doha Bay. The following year saw the duo return, this time playing on a "magic carpet" tennis court in the Souq Waqif. In 2011, the two came back and opened the new season on a court laid in the water of Doha Bay. The 2012 season was once again launched by both Federer and Nadal. This time, they played on a tennis court in the Katara Cultural Village amphitheatre.
