The New York City Fire Department or the Fire Department of New York City (FDNY) has the responsibility for protecting the citizens and property of New York City's five boroughs from fires and fire hazards, providing emergency medical services, technical rescue as well as providing first response to biological, chemical and radioactive hazards.

The FDNY is the largest municipal fire department in the world with approximately 11,400 uniformed officers and firefighters. It faces an extraordinarily varied challenge. In addition to responding to building types that range from wood-frame single family homes to high-rise structures, there are the many bridges and tunnels, large parks and wooded areas that can give rise to major brush fires, and the largest subway system on the planet. These challenges add yet another level of firefighting complexity and have led to the creation of the motto for FDNY firefighters of New York’s Bravest.
