Ár nDraíocht Féin

Ár nDraíocht Féin: A Druid Fellowship, Inc. (or ADF) is a non-profit religious organization based in the United States, dedicated to the study and further development of modern Druidry.

In Modern Irish, Ár nDraíocht Féin (pronounced [aːɾˠ ˌn̪ˠɾˠiːəxt̪ˠ ˈheːnʲ, -ˈfʲeːnʲ]) means "our own magic" (Druidism). "A Druid Fellowship" is therefore a backronym of "ADF". The organization was founded in 1983 and incorporated in 1990 as a U.S. 501(c)(3) non-profit organization by Isaac Bonewits. The organization's first public announcement and membership sign-up took place at the first WinterStar Symposium in 1984 at Burr Oak State Park in Glouster, Ohio. ADF was originally organized as an Association, with Articles of Association signed by all Trustees on April 18, 1987.

ADF is a neodruidic organization practicing a unique tradition of Neopagan Druidry and is mostly U.S.-based, with members and groups in most states and in several other countries as well. During the years 2000 through 2010 to the present, ADF's membership has remained well over 1000 persons, making it the largest public form of definitively Neopagan Druidism in the US.

Despite the Gaelic name, ADF Druidry actually encompasses all Indo-European religions, including Celtic, Germanic, Hellenic, Roman, Slavic, Gaulish, and Vedic religious practices. In that sense, ADF uses the term Druid as "a member of the Indo-European intelligentsia, especially of the clergy" or even more broadly as "a worshipper of Indo-European gods and goddesses". Strictly speaking, members of ADF are not only "druids", but are also members of related Indo-European religions which may have other terms for people in such clergy roles (e.g., gothi for clergy of ancient Norse religions).
