All around the world, Silsa (Silsa 
) is a rare primarily feminine, but very seldom masculine first name. The forename Silsa is characteristic of Nicaragua, where it is a rare feminine name, Peru, and Sweden. Not in comparison with a country's population, it most frequently occurs in Latin America and the Caribbean, particularly Brazil, Mexico, and Peru. Very seldom, Silsa is the last name as well as the forename.
