The Qatar Open, also known as the Qatar ExxonMobil Open for sponsorship reasons, is an ATP 250 category men's tennis tournament held annually in Doha since 1993. It traditionally takes place at the Khalifa International Tennis Complex in the first week of January and it is therefore one of the first tournaments of the year.

It was voted by tennis players as the best tournament in the ATP Tour 250 category in 2015, 2017, 2019, 2021 and 2022. The singles record is held by Roger Federer, who won the tournament 3 times. Rafael Nadal holds the record for most victories in doubles, with 4 hits.
