Globally, Cilsa (Cilsa 
) is a rare largely girly, but uncommonly masculine given name. The first name Cilsa is characteristic of Latin America and the Caribbean, particularly Nicaragua, where it is a rare girly name, Peru, where it is a very rare female name, and Brazil, where it is a very rare gender-neutral name. Not in comparison with a country's population, this name is the most popular in Brazil, Philippines, and Peru. Much less frequently, Cilsa is the last name as well as the forename.
