Arkady Romanovich Rotenberg is a Russian billionaire businessman and oligarch. With his brother Boris Rotenberg, he was co-owner of the Stroygazmontazh, the largest construction company for gas pipelines and electrical power supply lines in Russia.

Russian oligarchs are business oligarchs of the former Soviet republics who rapidly accumulated wealth in the 1990s via the Russian privatisation that followed the dissolution of the Soviet Union. The failing Soviet state left the ownership of state assets contested, which allowed for informal deals with former USSR officials as a means to acquire state property.
