The United States, Russia, Saudi Arabia, Canada, and Iraq were the world's top five oil producers in 2025, collectively accounting for over half of global output. These five nations produced 42.4 million barrels per day, representing 50.3% of the worldwide total, which averaged 84.5 million barrels daily. The U.S. led the pack with 13.7 million barrels per day, followed by Russia at 9.9 million, Saudi Arabia at 9.5 million, Canada at 5.0 million, and Iraq at 4.4 million.
While 99 countries contributed to oil production in 2025, the majority of output was concentrated among a handful of nations. The U.S. has maintained its position as the top producer since 2018, surpassing both Russia and Saudi Arabia. Global oil production reached an all-time high in 2025, marking a 3.1% increase from the previous year and an 11.4% rise from the 2020 low.
The Organization of the Petroleum Exporting Countries (OPEC) produced 30 million barrels per day in 2025, comprising 35.5% of the world's total output. OPEC, which as of 2026 includes 11 member countries, holds significant influence over oil prices by adjusting production targets among its members.
