So, you’re driving down the 605, probably stuck in that inevitable Southern California crawl, and you start wondering where the heck you actually are. Is this still L.A.? Or did I accidentally cross into Orange County while I was trying to find the right exit for the mall? It’s a common mix-up. If you’re looking for the quick answer, Cerritos is in Los Angeles County.
But honestly, the confusion is totally fair.
Cerritos sits right on the edge. It's one of those "Gateway Cities" that hugs the border so tightly you could practically throw a stone from a Cerritos park and have it land in La Palma or Buena Park—both of which are firmly in Orange County territory. Because of this geographic quirk, Cerritos often feels like a hybrid. It has that polished, master-planned vibe people usually associate with OC, yet it carries a 90703 or 90701 zip code and pays taxes to the County of Los Angeles.

The Borderland Identity of Cerritos
Geography is a funny thing in SoCal. Usually, the transitions between counties are invisible unless you’re looking at a map or notice the police cruisers change color. In Cerritos, the city is bounded by the San Gabriel River to the west and snuggles up against Artesia (which it actually surrounds on three sides like a doughnut).
To the south and east? That’s where things get blurry.
If you walk across certain residential streets, you’re suddenly in Cypress or La Palma. This proximity to Orange County is a big reason why the retail scene here is so massive. People from both counties flock to the Cerritos Auto Square and the Los Cerritos Center because it's the most convenient middle ground in the region.
A City Built on Milk (Seriously)
It’s hard to believe when you’re looking at the sleek, titanium-clad Cerritos Library, but this place used to be nothing but cows. Back in the day—we’re talking 1956—the city was incorporated under the name "Dairy Valley."
It wasn't a creative name, but it was accurate.
At one point, there were more than 400 dairies here. The "city" had more cows than people. It was the milk capital of the region. But as the post-WWII housing boom pushed people out of central L.A., those cow pastures became far more valuable as real estate. In 1967, the residents voted to change the name to Cerritos (Spanish for "little hills") to better reflect its new identity as a suburban sanctuary.

The name actually comes from Rancho Los Cerritos, a massive Spanish land grant that originally covered about 27,000 acres. Interestingly, the historic ranch house itself is actually located in Long Beach now, but the city of Cerritos kept the name to honor that heritage.
Why Everyone Thinks It’s in Orange County
There are a few reasons for the identity crisis.
- The Aesthetics: Cerritos is famously meticulously maintained. It’s been a "Tree City USA" since 1998. The parks are pristine, the streets are clean, and the landscaping is almost aggressively green. This "planned" feel is a hallmark of many Orange County cities like Irvine, so visitors often just assume they’ve crossed the line.
- The Shopping: The Los Cerritos Center is a major hub. Since it sits so close to the border, its marketing often targets the "North OC" crowd as much as the "Gateway Cities" crowd.
- The Schools: Cerritos is part of the ABC Unified School District. This district is legendary in California for its high performance (Whitney High School, anyone?). In Southern California, high-performing suburban school districts are often associated with the OC "bubble."
The "Experience" City
Cerritos doesn't just exist; it performs. Literally. The Cerritos Center for the Performing Arts is a world-class venue that draws big-name acts, but the real star of the city government’s portfolio is the library.
If you haven’t been, the Cerritos Library is basically a museum that happens to lend books.
It was one of the first "experience" libraries in the country. We're talking about a 15,000-gallon saltwater aquarium, a literal space shuttle model for kids, and an "Old World" reading room that looks like it was ripped straight out of a Harry Potter movie. This level of investment in public infrastructure is only possible because Cerritos is a retail powerhouse. The sales tax from the Auto Square—one of the highest-grossing auto malls in the world—funds a lifestyle that most other L.A. County cities can only dream of.
Moving Beyond the Basics
If you’re planning a visit or thinking about moving to the area, knowing what county Cerritos is in is just the start. You're looking at a community where over 60% of the population is Asian, creating a rich cultural tapestry that shows up in the local food scene. You can grab world-class Korean BBQ, head over for some incredible dim sum, or hit up a local Filipino spot all within a few blocks.
The city is also home to a sobering piece of history. In the Cerritos Sculpture Garden, there is a memorial for the 1986 Cerritos air disaster. It's a quiet, reflective spot that serves as a reminder of the community’s resilience.

- Visit the Library: Even if you don't have a library card, walk through the "Save the Planet" floor. It’s an architectural trip.
- Eat Local: Skip the chain restaurants at the mall and head to the smaller plazas along South Street or Pioneer Blvd. The variety of regional Asian cuisines is staggering.
- Check the Border: If you're a geography nerd, drive down Del Amo Blvd. You can literally watch the street signs change as you bounce between Cerritos, Lakewood, and La Palma.
- Catch a Show: The CCPA has acoustics that rival the best halls in Los Angeles proper, and parking is a hell of a lot easier than it is at the Disney Concert Hall.
Cerritos is the quintessential suburban success story of Los Angeles County. It managed to turn cow pastures into a high-tech, high-income hub without losing its soul to the generic sprawl. Whether you're there for the shopping or just trying to win a trivia night, you can now confidently say: it's L.A. County, through and through.
