Music Under New York (MUNY) is a part of the Arts & Design program by the Metropolitan Transportation Authority (MTA) that schedules musical performances in transportation hubs across its rapid transit, ferry, and commuter rail systems.

MTA grants every musician the legal right to perform, with or without MUNY affiliation. However, MUNY gives particular visibility and promotion to over 350 artists and groups who choose to participate. MUNY locations include approximately 30 high-traffic stations operated by the New York City Transit Authority that are part of the New York City Subway, the Long Island Rail Road, Metro-North Railroad, and the Staten Island Ferry.
