If you’re typing "county of amarillo texas" into a search bar, you’re looking for something that technically isn't on the map. Most people assume every major city in Texas sits neatly inside one county. Dallas is in Dallas County. El Paso is in El Paso County. But Amarillo? It’s a bit of a rebel. It straddles a line that splits its identity right down the middle, or close to it.
Amarillo is basically a tale of two counties: Potter and Randall.
Getting this wrong is more than just a trivia mistake. It actually dictates where you pay your taxes, which sheriff’s deputy pulls you over, and even which courthouse you have to visit for a marriage license. If you’re living on the north side of town, you’re a Potter County resident. If you head south across 10th Avenue or toward the growing suburban sprawl near Canyon, you’ve crossed into Randall.
The Weird Geography of the Texas Panhandle
The Texas Panhandle is a massive, windswept rectangle. It’s high plains country. When you look at a map of the county of Amarillo Texas area, you’ll see those perfectly square county lines that characterize the Llano Estacado. These lines were drawn by surveyors long before the city of Amarillo became the "Yellow Rose" of the plains.
Potter County was established in 1876 and organized in 1887. It was named after Robert Potter, a signer of the Texas Declaration of Independence. Randall County came along about the same time, named for Horace Randal, a Confederate brigadier general. The city of Amarillo grew up right on the border of these two administrative zones because of the railroads.
The Fort Worth and Denver City Railroad needed a hub. Where the tracks laid down, the people followed. By the late 1800s, Amarillo was becoming a cattle shipping powerhouse. Because the city expanded so rapidly, it simply ignored the lines on the map.
Today, the majority of the city's population actually lives in Randall County. However, the historic downtown, the massive Potter County Courthouse, and the original government hubs stay firmly in Potter. It’s a weirdly bifurcated existence. You can eat breakfast in Potter and work in Randall without ever leaving the city limits.
Why the split matters for locals
It’s honestly a bit of a headache for urban planning. Imagine trying to coordinate road repairs when the street is managed by two different sets of commissioners.
Public safety is another one. The Amarillo Police Department handles the city proper, but the Potter County Sheriff’s Office and the Randall County Sheriff’s Office have overlapping jurisdictions. If you’re out on the loop, you might see any of the three.
School districts don't follow county lines either. The Amarillo Independent School District (AISD) covers a huge chunk of the city, but as you move south into Randall County, you suddenly hit Canyon ISD territory. Many families specifically move to the south side of the city—the Randall County side—just to get their kids into Canyon schools. It's a huge driver of local real estate prices.
Potter County: The Rugged North
Potter County is where the grit is. It’s home to the Alibates Flint Quarries National Monument. This isn't just a pile of rocks. We are talking about a site where indigenous people harvested colorful flint for weapons and tools for over 13,000 years. It’s one of the oldest "industrial" sites in North America.
If you head north out of Amarillo into Potter, the landscape changes. The flat plains start to break. You get the Canadian River breaks, which are rugged, red-rock canyons that look like something out of an old Western.
- Population: Roughly 118,000.
- Key Sites: Cadillac Ranch, Downtown Amarillo, Tri-State Fairgrounds.
- Economy: Deeply tied to the medical district and government services.
The downtown area has seen a massive revitalization lately. The Hodgetown stadium—home to the Sod Poodles—sits in Potter. It’s brought a lot of life back to a part of town that was starting to feel a little dusty.
Randall County: The Suburban South
Randall County is the "growth" county. It’s where the new Starbucks pop up. It’s where the sprawling ranch-style homes with three-car garages are being built at a breakneck pace.
But the crown jewel of Randall County isn't a shopping mall. It’s Palo Duro Canyon State Park. Often called the "Grand Canyon of Texas," it is the second-largest canyon in the United States. It’s about 120 miles long and as much as 20 miles wide.
You haven't seen the Panhandle until you’ve stood on the rim of Palo Duro at sunset. The red clay, the yellow shales, and the purple siltstone all catch the light in a way that feels almost spiritual. It’s also the home of the "TEXAS" Outdoor Musical, which has been running for decades in a natural amphitheater inside the canyon.
The Canyon connection
Canyon, Texas, is the county seat of Randall. It’s a separate town from Amarillo but they’re basically merging at this point. Canyon is home to West Texas A&M University (WTAMU) and the Panhandle-Plains Historical Museum.
The museum is massive. Seriously. It’s the largest history museum in Texas. You could spend three days in there and still not see all the pioneer artifacts or the massive petroleum wing. It gives you a real sense of what it took to survive out here when there was nothing but grass and wind.
Common Misconceptions About the Area
When people search for information on the county of Amarillo Texas, they often bring a few myths with them. Let's clear some of those up.
Myth 1: It's always flat. Go to the north of Potter or the south of Randall. It’s anything but flat. The caprock escarpment creates dramatic drops and canyons that catch people off guard.
Myth 2: It’s just a stop on Route 66. While the Mother Road runs right through the heart of Potter County (check out the 6th Street Historic District), Amarillo is a modern economic hub. It’s a center for nuclear weapons assembly (Pantex), bell helicopter manufacturing, and a massive beef processing industry.

Myth 3: The weather is just "windy." Well, okay, it is windy. But it’s also volatile. You can have a 70-degree morning and a blizzard by 4:00 PM. The Texas Panhandle sits right in the heart of "Tornado Alley," though the storms here often move faster than they do in the South.
Navigating Government Services
If you are moving to the area or doing business here, you have to know which "county of Amarillo" you are dealing with.
Vehicle Registration: If you live north of 10th Ave, you go to the Potter County tax office. South? You’re going to the Randall County annex. Don't wait in the wrong line; they won't help you.
Court Systems: The 47th, 108th, 181st, 251st, and 320th District Courts serve both counties, but they operate out of specific buildings. Potter's courthouse is a beautiful, towering structure downtown. Randall's main legal hub is in Canyon.
Taxes: Potter County generally has a slightly different tax rate than Randall. Because Potter has more industrial and commercial property downtown, the burden is spread differently than in the residential-heavy Randall.
Practical Next Steps for Visitors or New Residents
- Check your address on a precinct map. Use the official City of Amarillo GIS maps to see exactly where your property line falls. This determines your voting precinct and your trash collection schedule.
- Visit both County Seats. Spend a morning in downtown Amarillo (Potter) to see the historic architecture, then drive 20 minutes south to Canyon (Randall) to visit the Panhandle-Plains Historical Museum.
- Prepare for the "Brownfield" effect. If you are buying land in Potter County, be aware of the agricultural zoning. Much of the land is still used for cattle and crops, which comes with specific Texas "Right to Farm" protections.
- Register your vehicle immediately. Texas is strict about this. You have 30 days. If you're in Randall, the annex on Western Street is usually faster than going all the way to Canyon.
Amarillo is a city of two halves. Understanding the Potter-Randall split is the only way to truly understand how the region functions. Whether you're here for the steaks at the Big Texan or a hike in the canyon, you're constantly weaving between two different Texas legacies.
