Garden Grove is a city in northern Orange County, California, United States. 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.

In 1933, much of the town's central business district was destroyed by the Long Beach earthquake, and one person was killed at the high school. The post-World War II boom led to rapid development, and Garden Grove was incorporated as a city in 1956 with about 44,000 residents.

In 1956, Orange County Plaza (now The Promenade) was opened at Chapman and Brookhurst, and upon its expansion in 1959, it had 60 stores, including a J. C. Penney, 2 variety stores and 2 supermarkets, and billed itself as both the largest and the first regional shopping center in Orange County.

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.

According to the United States Census Bureau, the city has a total area of 46.5 km (18.0 sq mi), 0.10% of which is water.

An annual event held over Memorial Day weekend, the Garden Grove Strawberry Festival is one of the largest community festivals in the western United States, attracting an estimated 250,000 visitors.

Part of the festivities include the cutting of the world's largest strawberry shortcake, carnival rides, food vendors, live music, and a celebrity-filled parade. Numerous Garden Grove organizations, including the Miss Garden Grove Scholarship Program, are part of the Memorial Day weekend festivities every year. In commemoration of Garden Grove's 50th anniversary, the city painted some of its fire hydrants with a design that featured a strawberry, recognizing the festival as a big part of Garden Grove's history.

Garden Grove uses a council-manager form of government. In July 2015, the city was sued by a resident who claimed that the longstanding at-large elections had affected the Latino vote and was in violation of the California Voting Rights Act.

The city council consists of mayor Steve Jones, Phat Bui, George S. Brietigam III, John R. O'Neill, Thu-Ha Nguyen, Stephanie Klopfenstein, and mayor pro tem Kim B. Nguyen.
