Nikolaev is an alternate transcription of the Russian surname Николаев (see Nikolayev) and the usual Bulgarian form. Both are patronymic surnames meaning "son of Nikolay," itself deriving from the given name Nicholas.The root name Nicholas comes from the Greek Νικόλαος (Nikolaos), composed of the elements νίκη (nike) meaning "victory" and λαός (laos) meaning "people", hence "victory of the people." This name gained immense popularity due to Saint Nicholas, a 4th-century bishop from Anatolia known for his generosity and the many miracles attributed to him. He is the patron saint of children, sailors, and merchants, and famously inspired the figure of Santa Claus.In Slavic countries, the name Nicholas was adopted early after Christianization, leading to many derivative given names and patronymic surnames. In Russian and Bulgarian cultures, the -ev/-ov suffix creates a patronymic meaning "son of." Thus, Nikolaev literally means "son of Nikolay." The Russian spelling Nikolayev is a variant; in Bulgaria, Nikolaev is the standard form.Feminine counterparts of this surname include the Bulgarian Nikolaeva, the Russian Nikolayeva, and also Nikolova (particularly common in Bulgaria and Macedonia). Other cognate surnames across the Slavic world include Serbian Nikolić, Slovak Mikula and Mikulová, and Danish Nikolajsen (from the Scandinavian given name Nikolaj).Meaning: Son of Nikolay (Nicholas), “victory of the people”Origin: Russian, BulgarianType: Patronymic surnameUsage: Common in Russia, Bulgaria, and among communities
