The Kirov Plant, Kirov Factory or Leningrad Kirov Plant (LKZ) (Russian: Кировский завод, romanized: Kirovskiy zavod) is a major Russian mechanical engineering and agricultural machinery manufacturing plant in St. Petersburg, Russia. It was established in 1789, then moved to its present site in 1801 as a foundry for cannonballs. The Kirov Plant is sometimes confused with another Leningrad heavy weapons manufacturer, Factory No. 185 (S.M. Kirov). Recently the main production of the company is Kirovets heavy tractors.

In 1917 the factory was an important center of the Red Guards formations.

In 1868 Nikolay Putilov (1820-1880) purchased the bankrupt plant; at the Putilov Works the Putilov Company (a joint-stock holding company from 1873) initially produced rolling stock for railways. The establishment boomed during the Russian industrialization of the 1890s, with the work-force quadrupling in a decade, reaching 12,400 in 1900. The factory traditionally produced goods for the Russian government, with railway products accounting for more than half of its total output. Starting in 1900 it also produced artillery, eventually becoming a major supplier of it to the Imperial Russian Army alongside the state arsenals. By 1917 it grew into a giant enterprise that was by far the largest in the city of St. Petersburg.

In December 1904, during the antecedent to the 1905 Russian Revolution, four workers at the plant, then called 'Putilov Ironworks', were fired because of their participation in strikes during Bloody Sunday. However, the plant manager asserted that they were fired for unrelated reasons. Virtually the entire workforce of the Putilov Ironworks went on strike when the plant manager refused to accede to their requests that the workers be rehired. Sympathy strikes in other parts of the city raised the number of strikers up to 150,000 workers in 382 factories. By 21 January [O.S. 8 January] 1905, the city had no electricity and no newspapers whatsoever and all public areas were declared closed.

Ships were built at the Putilov works in the early 20th century. The submarine tender Volkhov (later renamed Kommuna), built 1911–1915 at Putilov for the Imperial Russian Navy, remained in service of the Russian Navy in the 2010s.

In February 1917 strikes at the factory contributed to setting in motion the chain of events which led to the February Revolution.

After the October Revolution of November 1917 the establishment was renamed Red Putilovite Plant (zavod Krasny Putilovets) and became famous for its manufacture of the first Soviet tractors, Fordzon-Putilovets, based on the Fordson tractor. The Putilov Plant had a reputation for its revolutionary traditions.

In the wake of the December 1934 assassination of Sergey Kirov, the Leningrad Communist Party head, the plant was renamed Kirov Factory No. 100.

During World War II the plant manufactured the KV-1 tank.

In 1962 the factory produced the Kirovets K-700 tractor.

The Kirov Plant was de-listed from the Moscow Exchange in 2011.
