The Los Angeles Police Department (LAPD) is the police department of the City of Los Angeles, California. With over 9,600 officers and 3,000 civilian staff, covering an area of with a population of more than 3.5 million people, it is the fifth largest law enforcement agency in the United States (behind the New York City Police Department, Chicago Police Department, California Department of Corrections and Rehabilitation and the Federal Bureau of Investigation). The department has been heavily fictionalized in numerous movies and television shows. It has also been involved in a number of controversies, perhaps most notably the infamous Rodney King incident and the subsequent 1992 Los Angeles riots.

The LAPD should not be confused with the Los Angeles General Services Police.
