Around the world, Франсен (Francen 
, Franzén 
, Франсен 
) is a very rare gender-neutral forename. The given name Франсен is habitual in Sweden, where it is a rare boy's name, Philippines, where it is a very rare epicene name, and the United States, where it is an extremely rare principally female, but scarcely male name. Much more frequently, Франсен is the last name as well as the forename.
