新德鲁伊信仰（英语：Neo-druidism或neo-druidry）是指一种现代信仰型态，主张与大自然和谐共处，可追溯至17、18与19世纪的浪漫主义运动。最早的新德鲁伊信仰，是奠基于许多关于石器时代塞尔特文化的错误历史记载，与真正的古代塞尔特文化没有直接关系。

而较近代的新德鲁伊团体，则是采取了类似于塞尔特重建主义异教运动（Celtic Reconstructionist Paganism）的方式，创建出与史实更为贴近的行动。但是到目前为止，对于新德鲁伊信仰与史实的相近程度仍有争议。

2010年9月，英格兰与威尔斯慈善委员会（英国的独立部会，直接向国会与政府大臣负责）正式承认德鲁伊信仰为一种合法的宗教信仰，并允许与其他慈善宗教团体同样享有税负减免等优惠。 现代德鲁伊另有一支从古流传至今，经过1839年斯盖（sky）改革自称自然协会

Neo-Druidism or Neo-Druidry, commonly referred to as Druidry by many adherents, is a form of modern spirituality or religion that generally promotes harmony and worship of nature, and respect for all beings, including the environment. Many forms of modern Druidry are neopagan religions, whereas some are instead seen as philosophies that are not necessarily religious in nature. Originating in Britain during the 18th century, Druidry was originally a cultural movement, only gaining religious or spiritual connotations in the 19th century.
