The Los Angeles Fire Department provides firefighting services as well as technical rescue services, hazardous materials services and emergency medical services to the citizens of the city of Los Angeles, California, United States. The LAFD is responsible for approximately four million people who live in the agency's 471 square miles (1,220 km2) jurisdiction. The Los Angeles Fire Department was founded in 1886 and is the third largest municipal fire department in the United States, after the New York City Fire Department and the Chicago Fire Department. The department is sometimes also referred to as the Los Angeles City Fire Department or "LA City Fire" to distinguish it from the Los Angeles County Fire Department, which serves unincorporated areas and, via contracts, other incorporated municipalities within Los Angeles County without their own fire departments. The department is currently under the command of Chief Kristin Crowley.

The Los Angeles County Fire Department (LACoFD) provides firefighting and emergency medical services for the unincorporated parts of Los Angeles County, California, as well as 59 cities through contracting, including the city of La Habra, which is located in Orange County and is the first city outside of Los Angeles County to contract with LACoFD.
