Around the globe, Littlejohn (Littlejohn 
) is a very rare epicene forename. The forename Littlejohn is characteristic of the United States, where it is an extremely rare primarily boy's, but scarcely girly name, Nigeria, where it is an extremely rare unisex name, and China, where it is an extremely rare masculine name. Much more frequently, Littlejohn is the last name as well as the forename.
