Meaning & Origin

A female given name.

Jo is a girl's and boy's baby name of Hebrew origin, a short form of names like Josephine and Joanna, both ultimately rooted in the Hebrew name Yosef meaning 'God will increase.' Jo has a punchy, independent spirit that sets it apart from its longer source names.

The most famous literary Jo is undoubtedly Jo March from Louisa May Alcott's Little Women — a fiercely independent character who made this name synonymous with creativity and courage. As a stand-alone name it feels both vintage and refreshingly direct.
