PJSC Gazprom is a Russian majority state-owned multinational energy corporation headquartered in the Lakhta Center in Saint Petersburg. As of 2019, with sales over $120,000,000,000, it was ranked as the largest publicly listed natural gas company in the world and the largest company in Russia by revenue.

Gazprom was created in 1989, when the Soviet Ministry of Gas Industry was converted to a corporation, becoming the first state-run corporate enterprise in the Soviet Union. After the Soviet Union's dissolution, Gazprom was privatized, retaining its Russia-based assets. At that time, Gazprom evaded taxes and state regulation and engaged in asset stripping. The company later returned to government control in the early 2000s, and since then, the company is involved in the Russian government's diplomatic efforts, setting of gas prices, and access to pipelines.

The Gazprom name is a contraction of the Russian words gazovaya promyshlennost (газовая промышленность, gas industry). In January 2022, Gazprom displaced Sberbank from the first place in the list of the largest companies in Russia by market capitalization.

Gazprom is vertically integrated and is active in every area of the gas industry, including exploration and production, refining, transport, distribution and marketing, and power generation. In 2018, Gazprom produced twelve percent of the global output of natural gas. Gazprom is also a large oil producer through its subsidiary Gazprom Neft, producing about 41 million tons of oil with reserves amounting to 2 billion tons. The company also has subsidiaries in industrial sectors including finance, media and aviation, and majority stakes in other companies.

In the Global 2000 2022 list of Forbes, Gazprom was ranked 49^th of the largest companies in the world.
