Johanna is a feminine name, a variant form of Joanna that originated in Latin in the Middle Ages, including an -h- by analogy with the Latin masculine name Johannes. The original Greek form Iōanna lacks a medial /h/ because in Greek /h/ could only occur initially. For more information on the name's origin, see the article on Joanna.
