Oneida is an American experimental rock band from Brooklyn, New York, United States. Their influences include psychedelic rock, krautrock, electronic, noise rock, and minimalism, but the overall structure and intent of their music is not taken directly from any of these styles. Common elements found in their music include improvisation, repetition, driving rhythms, antique and analog equipment, and an overall eclecticism.

In the late 1990s, Oneida pioneered a culture of performance in nontraditional spaces throughout Brooklyn, NY, including warehouses, vacant theaters and storefronts, parking lots and garages, boats, and industrial facilities. They are recognized as the progenitors of what would become a thriving and widely influential Brooklyn experimental rock scene. They have also been recognized in gallery and museum culture, performing at the Guggenheim Museum, MoMA PS1, MassMOCA, and the Knovxille Museum of Art, among other fulsomely-endowed institutions.
