Willowbrook, alternatively named Willow Brook, is an unincorporated community and census-designated place (CDP) in Los Angeles County, California, United States. The population was 24,295 at the 2020 census, down from 35,983 at the 2010 census.

Willowbrook is the home to the newly renovated Martin Luther King Jr. Outpatient Center. Also located in Willowbrook is the Charles R. Drew University of Medicine and Science, which oversees residency training programs, allied health programs, a medical education program (jointly with the University of California, Los Angeles), a medical magnet high school, the area Head Start program, and various centers for health disparities research. Due to severe deficiencies, the former King/Drew Medical Center lost accreditation of several key residency training programs.
