Hart Memorial Park (commonly called Hart Park) is a large public park in Kern County, California. It is located just north of Bakersfield (specifically the Northeast region). The park is 370 acres (150 ha), and contains two lakes and three canals. It was named after County Supervisor John Hart, who spearheaded the project. Constructed between 1921 and 1936, it is the oldest section of the Kern River County Park.
