In the entire world, Ruska (Руска 
, Ruska 
, რუსკა 
) is a common principally feminine, but very seldom boy's first name. The forename Ruska is characteristic of Bulgaria, where it is a common feminine name, Cyprus, where it is quite a rare female name, and Greece, where it is a rare girly name. Not in comparison with a country's population, it is the most numerous in Bulgaria, the Democratic Republic of the Congo, and Indonesia. Likewise, Ruska is the last name as well as the forename.
