Nikoni wa Sparta (930 hivi - Sparta, Ugiriki, 998) alikuwa mmonaki aliyeishi miaka mingi bila makao maalumu, akikariri daima "Tubuni!" katika hotuba zake. Hatimaye alianzisha monasteri huko Sparta, alipofariki dunia. Tangu kale anaheshimiwa na Wakatoliki na Waorthodoksi kama mtakatifu. Sikukuu yake ni tarehe 26 Novemba.
