Svetlana (Cyrillic: Светлана) is a common Orthodox Slavic feminine given name, deriving from the East and South Slavic root svet (Cyrillic: свет), meaning "light", "shining", "luminescent", "pure", "blessed", or "holy", depending upon context similar if not the same as the word Shweta in Sanskrit. Particularly unique among similar common Russian names, this one is not of ancient Slavic origin, but was coined by Alexander Vostokov in 1802 and popularized by Vasily Zhukovsky in his eponymous ballad "Svetlana", the latter first published in 1813.
