Globally, Geraldin (Geraldin 
) is quite a common unisex given name. The given name Geraldin is characteristic of Reunion, where it is quite a common girly name, Colombia, where it is quite a rare girly name, and Philippines, where it is quite a rare principally girly, but scarcely male name. Not in comparison with a country's population, it is commonest in Philippines, Colombia, and the Democratic Republic of the Congo. Much less frequently, Geraldin is the last name as well as the forename.
