Throughout the world, Leónidas (Leónidas 
, Леонидас 
) is a rare largely male, but infrequently feminine given name. The first name Leónidas is habitual in the Dominican Republic, where it is a rare unisex name, Lithuania, where it is a rare masculine name, and Guatemala. In absolute terms, it is commonest in Latin America and the Caribbean, particularly the Dominican Republic, Guatemala, and Bolivia. Very seldom, Leónidas is the last name as well as the forename.
