This list is based on theCIA World Factbook (when no citation is given).^[1] or other authoritative third-party sources (as cited). Based on data fromEIA, at the start of 2021, proven gas reserves were dominated by three countries:Iran,Russia, andQatar.

There is some disagreement on which country has the largest proven gas reserves. Sources that consider Russia in possession of the world's largest proven reserves include the US CIA (47,600 cubic kilometers),^[2] the USEnergy Information Administration (EIA) (49,000 km³),^[3] and OPEC (48,810 km³).^[4] However,BP credits Russia with only 32,900 km³,^[5] which would place it in second place, slightly behind Iran (33,100 to 33,800 km³, depending on the source).

Due to constant announcements ofshale gasrecoverable reserves, as well as drilling in Central Asia, South America, Africa, anddeepwater drilling, estimates are updated frequently. Since 2000, some countries, notably the US and Canada, have seen large increases in proven gas reserves due to development ofshale gas, but shale gas deposits in most countries are yet to be added to reserve calculations.

Note:* indicates that the linked article is about natural gas production in the country or territory specifically, such asnatural gas in Russia.
