The Central Park Medical Unit (CPMU) is an all-volunteer ambulance service that provides completely free emergency medical service to patrons of Central Park and the surrounding streets, in Manhattan, New York City, United States.

Many of these calls are true medical emergencies resulting in life saving care—which represents over two and a half million dollars in free care to the people of New York City.

CPMU has also helped the greater New York City community during the 1993 World Trade Center bombing, the September 11, 2001 attacks on the World Trade Center, the American Airlines Flight 587 crash, the 2003 North America blackout as well as Hurricane Sandy.

"[2] The Central Park Medical Rescue Squad was primarily a first response unit that consisted of approximately twenty volunteers, a few personal bicycles and a retrofitted Ford van used to transport crews and equipment.

In 1976, the Central Park Medical Rescue Squad purchased a used type II ambulance from Lenox Hill Hospital.
