Norilsk Nickel (MICEX-RTS: GMKN / LSE: MNOD) (Russian: ГМК «Норильский Никель») is a Russian nickel and palladium mining and smelting company. Its largest operations are located in the Norilsk–Talnakh area, in northern Russia. MMC stands for "Mining and Metallurgical Company".

Norilsk Nickel is headquartered in Moscow and is the world's leading producer of nickel and palladium. The company is also active in platinum, copper and cobalt. It is ranked among the top four world platinum producers, in association with subsidiary Stillwater Mining Company of Billings, Montana. It is ranked among the top ten copper producers.

The company is listed on MICEX-RTS and the NASDAQ. The key shareholders are Vladimir Potanin's Interros and Oleg Deripaska's Rusal: each reportedly owns over 25% of shares. In December 2010, Norilsk offered to buy out Rusal's share for US$12 billion; but the offer was declined.

Mining began in the Norilsk area in the 1920s. The government of the USSR created the "Norilsk Combine" in 1935 and passed control to the NKVD at that time. In 1943 Norilsk produced 4 thousand tons of refined nickel and in 1945 hit the target figure of ten thousand tons. Mining and metal production continued first with Gulag forced labour, later with much volunteer labour, owing to the comparatively good wages offered.

Norilsk (Russian: Нори́льск; IPA: [nɐˈrʲilʲsk]) is an industrial city in Krasnoyarsk Krai, Russia, located between the Yenisei River and the Taymyr Peninsula. Population: 175,301 (2010 Census preliminary results); 134,832 (2002 Census); 174,673 (1989 Census).

Norilsk is the northernmost city in Siberia and the world's second largest city (after Murmansk) north of the Arctic Circle. Norilsk, Yakutsk, and Vorkuta are the only large cities in the continuous permafrost zone.

Geographically, it lies between Taymyrsky Dolgano-Nenetsky District to its north, and Turukhansky District to its south.

Norilsk was founded by the end of the 1920s; however, the official date of founding is traditionally set to 1935, when Norilsk was expanded as a settlement for the Norilsk mining-metallurgic complex and became the center of the Norillag system of GULAG labor camps.^{[citation needed]} It was granted the urban-type settlement status in 1939 and town status in 1953.^{[citation needed]}

Norilsk, located between the West Siberian Plain and Central Siberian Plateau at the foot of the 1,700-meter (5,600 ft) high Putoran Mountains, is situated on some of the largest nickel deposits on Earth. Consequently, mining and smelting ore are the major industries. Norilsk is the center of a region where nickel, copper, cobalt, platinum, palladium, and coal are mined. Mineral deposits in the Siberian Craton had been known for two centuries before Norilsk was founded, but mining began only in 1939, when the buried portions of the Norilsk-Talnakh intrusions were found beneath mountainous terrain.
