Garden Grove is a city in northern Orange County, California, United States, located 34 miles (55 km) southeast of the city of Los Angeles in the Los Angeles metropolitan area. The population was 171,949 at the 2020 census. State Route 22, also known as the Garden Grove Freeway, passes through the city in an east–west direction. The western portion of the city is known as West Garden Grove.

Garden Grove was founded by Alonzo Cook in 1874. A school district and Methodist church were organized that year. It remained a small rural crossroads and farming community until the arrival of the Pacific Electric Railroad in 1905. The rail connection helped the town prosper with the influx of tourists, visitors and eventually settlers, and it was noted for its crops of oranges, walnuts, chili peppers and later strawberries.

Garden Grove has a rugged set of boundaries with many panhandles. The West Garden Grove neighborhood is west of Beach Boulevard and is largely separated from the rest of Garden Grove by the city of Stanton, with a small bridge of jurisdiction linking the two along Garden Grove Boulevard. A panhandle in the southern part of the town's borders situated between Westminster's Ward Street to the west and Santa Ana's Euclid Street to the east creates a small border with the city of Fountain Valley. Other neighboring cities include Cypress and Anaheim to the north, Orange to the east, and the cities of Seal Beach and Los Alamitos to the west.
