The Green Man is a legendary being primarily interpreted as a symbol of rebirth, representing the cycle of new growth that occurs every spring. The Green Man is most commonly depicted in a sculpture as a face completely surrounded by leaves.

Carvings of the Green Man may take many forms, naturalistic or decorative. The simplest are a man's face peering out of dense foliage. Some may have leaves for hair, perhaps with a leafy beard. Often leaves or leafy shoots are shown growing from his open mouth and sometimes even from the nose and eyes as well. In the most abstract examples, the carving at first glance appears to be merely stylised foliage, with the facial element only becoming apparent on closer examination. The face is almost always male; green women are rare.

For many modern Pagans, the Green Man is used as a symbol of seasonal renewal and ecological awareness.

In Wicca, the Green Man has often been used as a representation of the Horned God, a syncretic deity that incorporates aspects of, among others, the Celtic Cernunnos and the Greek Pan.
