Leonid Vasyliovych Derkach (Ukrainian: Леонід Васильович Деркач; 19 July 1939 – 14 January 2022) was a Soviet and Ukrainian politician, intelligence officer, and general who was Head of the Security Service of Ukraine from 22 April 1998 to 10 February 2001. Called the "Ukrainian Sorge" (Russian: "Украинский Зорге"), he headed one of the five groups in the Dnipropetrovsk Mafia. The Derkach family maintains very close relationships with Oleg Deripaska, Mikhail Fridman's Moscow-based Alfa Group and Petr Aven's Alfa-Bank.

Both Leonid and Andrii Derkach were also close to Vadim Rabinovich as well as Semyon Mogilevich, Alexander Angert, Leonid Minin, and Sergei Mikhailov, members of the Russian, Ukrainian, and Israeli mafias.
