The Aghori (from Sanskrit ; ) are a monastic order of ascetic Shaivite sadhus based in Uttar Pradesh, India. They are the only surviving sect derived from the Kāpālika tradition, a Tantric, non-Puranic form of Shaivism which originated in Medieval India between the 7th and 8th century CE. Similarly to their predecessors, Aghoris usually engage in post-mortem rituals, often dwell in charnel grounds, smear cremation ashes on their bodies, and use bones from human corpses for crafting kapāla (skull cups which Shiva and other Hindu deities are often iconically depicted holding or using) and jewellery. Their practices are sometimes considered contradictory to orthodox Hinduism. Many Aghori gurus command great reverence from rural populations and are widely referred to in medieval and modern works of Indian literature, as they are supposed to possess healing powers gained through their intensely eremitic rites and practices of renunciation and tápasya.

Aghori rituals, which are performed precisely to oppose notions of purity commonplace in orthodox Hinduism, are typically macabre in nature. The practices of Aghoris vary and include living in cemeteries, smearing cremation ashes on their bodies, using human skulls for decoration and bowls, smoking marijuana, drinking alcohol, and meditating on top of corpses. Although contrary to mainstream Hinduism, these practices exemplify the Aghori philosophy of criticizing commonplace social relations and fears through the use of culturally offensive acts. Furthermore, they demonstrate the Aghoris' acceptance of death as a necessary and natural part of the human experience. The Aghori tradition is basically categorized under the shamanic marg of sadhana. Aghoris are not to be confused with Shivnetras, who are also ardent devotees of Shiva, but do not indulge in extreme, tamasic ritual practices. Although the Aghoris enjoy close ties with the Shivnetras, the two groups are quite distinct, Shivnetras engaging in sattvic worship. Aghoris base their beliefs on two principles common to broader Shaiva beliefs: that Shiva is
