Malibu is a beach city in the Santa Monica Mountains region of Los Angeles County, California, about 30 miles (48 km) west of Downtown Los Angeles. It is known for its Mediterranean climate, its strip of beaches stretching 21 miles along the Pacific Ocean coast, and for its longtime status as the home of numerous affluent Hollywood celebrities and executives. Although a high proportion of its residents are entertainment industry figures with million-dollar mansions, Malibu also features several middle- and upper-middle-class neighborhoods. The Pacific Coast Highway traverses the city and has led most residents to settle anywhere from half a mile to within a few hundred yards of it, with some residents living up to one mile away from the beach in areas featuring narrow canyons. As of the 2020 census, the city's population was 10,654.

The Santa Monica Mountains are a coastal mountain range in Southern California, next to the Pacific Ocean. It is part of the Transverse Ranges. The Santa Monica Mountains National Recreation Area encompasses this mountain range. Because of its proximity to densely populated regions, it is one of the most visited natural areas in California.
