The Wagner Group, officially known as PMC Wagner, is a Russian state-funded private military company (PMC) controlled until 2023 by Yevgeny Prigozhin, a former close ally of Russia's president Vladimir Putin. The Wagner Group has used infrastructure of the Russian Armed Forces. Evidence suggests that Wagner has been used as a proxy by the Russian government, allowing it to have plausible deniability for military operations abroad, and hiding the true casualties of Russia's foreign interventions.

Yevgeny Viktorovich Prigozhin was a Russian mercenary leader and oligarch. He led the Wagner Group private military company and was a close confidant of Russian president Vladimir Putin until launching a rebellion in June 2023. Prigozhin was sometimes referred to as "Putin's chef" because he owned restaurants and catering businesses that provided services to the Kremlin. Once a convict in the Soviet Union, Prigozhin controlled a network of influential companies whose operations, according to a 2020 investigation, were "tightly integrated with Russia's Defence Ministry and its intelligence arm, the GRU".
