A trance party is a type of electronic dance music event that originated in the early 1990s in the Indian state of Goa. It is characterized by long songs built on progressive beat changes that are said to put the listener in a "trance". Goa trance often has drone-like basslines, similar to the techno minimalism of 21st century psychedelic trance (psytrance) . Psychedelic trance developed from Goa trance.

While some people may associate trance parties with spirituality or family gatherings, they are primarily social events where people go to have fun, listen to music, make friends, and dance. Trance parties are not necessarily spiritual gatherings or families.

Trance parties are often held in clubs or outdoor locations, and DJs are the preferred format for music. Vocal samples are often used in Goa trance, and they mostly contain references to drugs, parapsychology, extraterrestrial life, existentialism, out-of-body experiences, dreams, science, time travel, spirituality, and similarly mysterious and unconventional topics.
