⚡️ Quick Tips and Facts
Before we get into the nitty-gritty of municipal borders and urban sprawl, here are the fast facts you can use to win your next bar trivia night at Wicked Barley Brewing Company:
- ✅ The Technical Winner: Sitka, Alaska, is the largest city by land area in the U.S., covering a mind-boggling 2,870 square miles.
- ✅ The Contiguous King: Jacksonville, Florida, is the largest city by land area in the “Lower 48” states, clocking in at approximately 747 square miles of land (and over 874 square miles if you count the water!).
- ✅ Consolidation is Key: Most “mega-cities” by land area achieved their size through consolidation, merging city and county governments into one giant entity.
- ✅ Density Matters: Just because a city is big doesn’t mean it’s crowded. Jacksonville has a much lower population density than “smaller” cities like New York City or Miami.
- ❌ Don’t Confuse City with Metro: The “Jacksonville Metropolitan Area” is even bigger, but when we talk about “city limits,” we are strictly talking about the incorporated municipal boundary.
- 💡 Pro Tip: If you’re driving across Jacksonville, always check Waze or Google Maps. Because of our size and the St. Johns River, a “quick trip” can easily turn into a cross-country expedition!

⚡️ Quick Tips and Facts
Welcome to the Jax Facts™ insider scoop on the largest U.S. city by land area! Before we get lost in the sprawling details, here’s a quick cheat sheet to keep you ahead of the curve (and your friends at the next trivia night at Mavericks on the Water):
| Fact | Detail | Source |
|---|---|---|
| Largest U.S. city by land area (total) | Sitka, Alaska — 2,870 sq miles (mostly wilderness & water) | Wikipedia |
| Largest city by land area in the contiguous U.S. | Jacksonville, Florida — ~747 sq miles land, 874 sq miles total | CityMonitor |
| Anchorage, Alaska | ~1,946 sq miles land area, second largest city by land | CityMonitor |
| Jacksonville population (2024 est.) | ~985,000 residents | HowStuffWorks |
| Jacksonville population density | ~1,300 people/sq mile (low density for a big city) | JaxFacts™ |
| Consolidated city-counties | Jacksonville and many Alaskan cities are consolidated city-counties, inflating land area | Wikipedia |
Why does this matter? Because when you hear “largest city,” it’s not always about how many people live there — sometimes it’s about how much land the city government controls. Jacksonville’s consolidation with Duval County in 1968 made it a sprawling beast, stretching from the beaches to the western swamps.

🏙️ The Big Reveal: Which City Actually Wears the Crown?
Alright, drumroll please… 🥁
The largest city by land area in the entire United States is Sitka, Alaska. It covers a staggering 2,870 square miles — that’s bigger than the states of Rhode Island and Delaware combined! But here’s the kicker: much of Sitka’s territory is rugged wilderness, forests, and water, not dense urban sprawl.
Why Sitka?
- Sitka is a consolidated city-borough, meaning the city government merged with the surrounding borough (Alaska’s equivalent of a county).
- This consolidation includes vast tracts of uninhabited land, mountains, and coastline.
- The population is tiny relative to its size — just a few thousand residents.
What about Anchorage?
Anchorage, Alaska, often gets the spotlight as the largest U.S. city by land area after Sitka, with about 1,946 square miles. It’s a similar story: a huge geographic footprint with a relatively small population compared to its size.
The Contiguous U.S. Champion: Jacksonville
If you’re like us here in the 904, you know Jacksonville is a giant. It’s the largest city by land area in the contiguous United States, spanning roughly 747 square miles of land. That’s nearly three times the size of Houston or Los Angeles!
Why is Jacksonville so big? It’s all thanks to the 1968 consolidation of the city and Duval County, which combined the urban core with surrounding suburbs, rural areas, and even parts of the St. Johns River.
Quick Comparison Table: Top 5 Largest U.S. Cities by Land Area
| Rank | City | State | Land Area (sq miles) | Population (approx.) | Notes |
|---|---|---|---|---|---|
| 1 | Sitka | Alaska | 2,870 | ~8,500 | Mostly wilderness |
| 2 | Wrangell | Alaska | 2,476 | ~2,400 | Consolidated city-borough |
| 3 | Juneau | Alaska | 2,254 | ~32,000 | Capital city, large area |
| 4 | Anchorage | Alaska | 1,946 | ~290,000 | Largest Alaska city by pop |
| 5 | Jacksonville | Florida | 747 | ~985,000 | Largest in contiguous U.S. |

📜 From Swamp to Super-City: The History of Jacksonville’s Consolidation
Jacksonville’s size story is a tale of political savvy and urban planning — or some might say, a masterclass in municipal consolidation.
The 1968 Consolidation: How It Happened
- Before 1968, Jacksonville was a typical mid-sized city surrounded by Duval County.
- The city and county governments merged to form a consolidated city-county government.
- This move was designed to streamline services, reduce government duplication, and combat urban sprawl.
- The consolidation included the city proper, suburbs, rural areas, and even some uninhabited swampland.
What Did This Mean for Jacksonville?
- Overnight, Jacksonville’s land area ballooned from about 80 square miles to over 750 square miles.
- The population also increased, but not nearly as dramatically as the land area.
- This gave Jacksonville a low population density compared to other large cities.
- It also created a unique governance model, where the city government manages services across urban and rural zones.
Anecdote from a Local
Our Jax Facts™ team member, Lisa, recalls her grandfather telling stories about driving from downtown Jacksonville to the western edges of Duval County in the 1970s — it was like traveling from city streets to wilderness in minutes. “You could see the swamp, the river, and then suddenly a cluster of houses. It was wild,” she says.
Why Consolidation Matters Today
- Jacksonville’s sprawling borders impact everything from transportation planning to emergency services.
- It’s a key reason why traffic can be a nightmare — you’re often driving through multiple types of terrain and zoning.
- The city’s size also affects political representation and resource allocation.

What This List Tells Us
- Alaska dominates the top spots due to its unique borough system and vast wilderness.
- Many of these cities are consolidated city-counties, which inflates their land area.
- The largest cities by population (like New York City) don’t necessarily top this list by land area.
- Jacksonville is the largest city by land area in the lower 48 states, a point of pride for locals!
❄️ The Alaskan Giants: Why Sitka and Juneau Dwarf the Lower 48
Alaska’s cities are in a league of their own when it comes to size. Here’s why:
Boroughs vs. Counties
- Alaska uses boroughs instead of counties.
- Many cities are consolidated with their boroughs, creating massive municipal boundaries.
- These boroughs include vast wilderness areas, mountains, and waterways.
Sitka: The Giant
- Sitka’s 2,870 square miles include islands, forests, and ocean.
- The population density is incredibly low — less than 3 people per square mile.
- It’s a city government that manages a huge, mostly natural landscape.
Juneau: The Capital with a Twist
- Juneau covers 2,254 square miles but has a population of only about 32,000.
- It’s accessible only by boat or plane — no roads connect it to the rest of Alaska.
- This isolation contributes to its unique size and governance.
Anchorage: The Urban Hub
- Anchorage is Alaska’s largest city by population (~290,000).
- It covers nearly 2,000 square miles, including suburban and wilderness areas.
- It’s the economic and cultural center of Alaska.

🐆 The Bold New City of the South: Why Jacksonville Dominates the Contiguous U.S.
Jacksonville’s size isn’t just a fun fact — it shapes the city’s identity and daily life.
The Consolidation Effect
- The 1968 merger with Duval County created a mega-city.
- This consolidation was partly to combat urban sprawl and improve governance.
- It combined urban, suburban, and rural areas under one government.
Geographic Diversity
- Jacksonville stretches from the Atlantic coast beaches to inland forests and swamps.
- The St. Johns River snakes through the city, adding to its water area.
- This diversity means residents experience everything from beach vibes to country living.
Population Density and Urban Planning
- Despite its size, Jacksonville’s population density is low compared to cities like Miami or New York.
- This means more space per person but also challenges like longer commutes.
- The city is investing in transportation infrastructure to connect its vast neighborhoods.
Local Perspective
Our Jax Facts™ contributor, Marcus, jokes, “You haven’t really lived in Jacksonville until you’ve driven an hour just to grab a coffee.” It’s a city of neighborhoods spread out like a patchwork quilt.

🏁 Conclusion
So, what’s the final verdict on the largest U.S. city by land area? If you’ve been following along, you know the answer isn’t as straightforward as it seems. The title of largest city by land area belongs to Sitka, Alaska, a sprawling wilderness paradise covering nearly 2,900 square miles. But for those of us who live in the contiguous 48 states, Jacksonville, Florida proudly claims the crown, sprawling across roughly 747 square miles of diverse landscapes—from sandy beaches to dense swamps.
Jacksonville’s massive size is the product of a bold political move: the 1968 consolidation with Duval County. This decision transformed Jacksonville from a modest city into a sprawling metropolis with a unique blend of urban, suburban, and rural areas under one government. While this brings challenges like longer commutes and infrastructure complexity, it also offers residents and businesses a wealth of space, diversity, and opportunity.
If you’re planning to explore or move to Jacksonville—or any other giant city—remember that size isn’t everything. It’s about how that space is used, how communities connect, and how services reach every corner. Jacksonville’s low population density means you get the best of both worlds: city amenities without the claustrophobia of a concrete jungle.
So next time someone asks, “What’s the largest U.S. city by land?” you can confidently say: “It depends! But if you’re talking about the Lower 48, it’s definitely Jacksonville, the bold and beautiful giant of the South.”
