Oleg Petrovich Fomenko (Russian: Олег Петрович Фоменко; born 3 August 1972) is a Russian football coach and a former player. He is an assistant coach with PFC CSKA Moscow.
He played 8 seasons in the second-tier Russian Football National League debut for 6 different teams.
After the caretaking spell for FC Krasnodar manager Murad Musayev expired on 4 May 2018, Fomenko was officially registered with the Russian Premier League as the manager (head coach) of Krasnodar, with Musayev re-registered as his assistant, as Fomenko possessed the necessary UEFA Pro Licence at the time and Musayev did not. Despite the formal role adjustment, Musayev continued to manage the team and Fomenko to act as his assistant. Before the 2019–20 season, Fomenko was reassigned to coaching FC Krasnodar-2. He left Krasnodar by mutual consent on 30 October 2019.[1]
