Shamanism is a religious practice that involves a practitioner (shaman) interacting with the spirit world through altered states of consciousness, such as trance. The goal of this is usually to direct spirits or spiritual energies into the physical world for the purpose of healing, divination, or to aid human beings in some other way. Beliefs and practices categorized as "shamanic" have attracted the interest of scholars from a variety of disciplines, including anthropologists, archeologists, historians, religious studies scholars, philosophers and psychologists. Hundreds of books and academic papers on the subject have been produced, with a peer-reviewed academic journal being devoted to the study of shamanism. In the 20th century, non-Indigenous Westerners involved in countercultural movements, such as hippies and the New Age created modern magicoreligious practices influenced by their ideas of various Indigenous religions, creating what has been termed neoshamanism or the neoshamanic movement. It has affected the development of many neopagan practices, as well as faced a backlash and accusations of cultural appropriation, exploitation and misrepresentation when outside observers have tried to practice the ceremonies of, or represent, centuries-old cultures to which they do not belong.

The etymology of the word is sometimes connected to the Tungus root , meaning "to know". However, Finnish ethnolinguist Juha Janhunen questions this connection on linguistic grounds: "The possibility cannot be completely rejected, but neither should it be accepted without reservation since the assumed derivational relationship is phonologically irregular (note especially the vowel quantities)." Mircea Eliade noted that the Sanskrit word śramaṇa, designating a wandering monastic or holy figure, has spread to many Central Asian languages along with Buddhism and could be the ultimate origin of the word shaman. The term was adopted by Russians interacting with the Indigenous peoples in Siberia. It is found in the memoirs of the exiled Russian churchman Avvakum. It was brought to Western Europe twenty years later by the Dutch traveler Nicolaes Witsen, who reported his stay and journeys among the Tungusic- and Samoyedic-speaking Indigenous peoples of Siberia in his book Noord en Oost Tataryen (1692). Adam Brand, a merchant from Lübeck, published in 1698 his account of a Russian embassy to China; a
