Fern (also Stichting Fern is a Dutch foundation created in 1995. It is an international non-governmental organization to keep track of the EU's involvement in forests and to coordinate NGO activities at the European level. Through its work, Fern aims to increase the political and economic opportunities for people to create a more balanced society in which human rights are fully respected and environmental and social values are fully integrated.

A fern is a member of a group of approximately 12,000 species of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular (i.e. having water-conducting vessels). They have stems and leaves, like other vascular plants. Most ferns have what are called fiddleheads that expand into fronds, which are each delicately divided.
