Arkady Romanovich Rotenberg (Russian: Аркадий Романович Ротенберг; born 15 December 1951) is a Russian billionaire businessman and oligarch. With his brother Boris Rotenberg, he was co-owner of the Stroygazmontazh (S.G.M. group), the largest construction company for gas pipelines and electrical power supply lines in Russia.
In 2023 Forbes estimated Rotenberg's wealth at $3.5 billion. He is a close confidant, business partner, and childhood friend of president Vladimir Putin. Rotenberg became a billionaire through lucrative state-sponsored construction projects and oil pipelines. The Pandora Papers leak implicated Rotenberg in facilitating and maintaining elaborate networks of offshore wealth for Russian political and economic elites.
