Aleksey Borisovich Mozgovoy[a] (Russian: Алексе́й Бори́сович Мозгово́й; Ukrainian: Олексі́й Бори́сович Мозгови́й, romanized: Oleksii Borysovych Mozghovyi; 3 April 1975 – 23 May 2015) was a commander of the Russian-installed separatist Luhansk People's Republic in Ukraine.

[5] Mozgovoy was born in the village of Nyzhnia Duvanka, Svatove Raion, Luhansk Oblast located in the eastern part of Ukraine.

[9][10] Prior to his death, Mozgovoy's Prizrak brigade had been having supply issues due to his refusal to join the formal LPR power structure.

[17] Surviving leaders of the Prizrak Brigade stated that Ukrainian commandos were responsible, and they called on their supporters not to spread false rumors.

[18] Anton Gerashchenko, the adviser to the Ukrainian minister for internal affairs, said Mozgovoy had been assassinated by Russian GRU special forces.

[20] In 2020 a court in the unrecognized Luhansk People's Republic determined that Mozgovoy and fellow Prizrak brigade member Aleksandr Kostin had planned and commanded the 2014 ambush and murder of a family for cash.

[4] In October 2014 Mozgovoy presided over a so-called "people's court" (Russian: Народный суд) that issued a death sentence against a suspect accused of rape by asking the audience to raise hands.

The statement that caused the controversy was: If tomorrow I see in a cafe, in a pub even one young lady, she will be arrested ... А woman should be the guardian of the hearth, the mother.
