Topanga (Tongva: Topaa'nga) is an unincorporated community in western Los Angeles County, California, United States. Located in the Santa Monica Mountains, the community exists in Topanga Canyon and the surrounding hills. The narrow southern portion of Topanga at the coast is between the city of Malibu and the Los Angeles neighborhood of Pacific Palisades. For statistical purposes, the United States Census Bureau has defined Topanga as a census-designated place (CDP). As of the 2020 census the population of the Topanga CDP was 8,560. The ZIP code is 90290 and the area code is primarily 310, with 818 only at the north end of the canyon. It is in the 3rd County Supervisorial district.
Topanga is the largest unincorporated area in Los Angeles County by area, although a majority of it is undeveloped. The 2025 Palisades Fire severely impacted the community with the devastation of structures destroyed, forcing evacuations, and multiple road closures.
