It is wild how much Tennessee has changed in just the last few years. If you haven't been to Nashville or Knoxville lately, you might not even recognize certain neighborhoods. Cranes are everywhere. Traffic that used to be a "five-minute delay" is now a legitimate "leave an hour early" situation. People are flocking here, and it's not just for the music or the lack of state income tax—though, honestly, that helps a lot.
So, what are the biggest cities in Tennessee right now?
Most people just think of Nashville and Memphis, and while they definitely lead the pack, the "big city" landscape in the Volunteer State is shifting. We’re seeing massive suburban explosions and a weirdly specific migration toward East Tennessee.
1. Nashville: The Unstoppable "Music City"
Nashville isn't just a city anymore; it’s a machine. As of early 2026, Nashville-Davidson sits comfortably as the largest city in the state with a population pushing toward 715,000 residents.
It’s been the heavyweight champion since it officially overtook Memphis around 2016. But the raw number of people living in the city limits doesn't tell the whole story. The entire metro area is massive. You've got folks living in places like Murfreesboro and Franklin who basically treat Nashville like their backyard.
Why is it so big? Basically, jobs. Healthcare, tech, and of course, the entertainment industry. It’s also become a "bachelorette party capital," which residents have feelings about (mostly annoyed ones), but the money it brings in is undeniable. If you’re looking for where the action is, this is it.

2. Memphis: The Soul of the Mississippi
Memphis is currently the second-largest city, hovering around 620,000 to 630,000 people. It’s got a totally different vibe than Nashville. It feels more "real" to a lot of people—grittier, soulful, and deeply rooted in history.
While Nashville is booming with new builds, Memphis is more about its legacy. It’s a global logistics hub thanks to FedEx, which keeps the economy humming. However, it’s worth noting that while Nashville is growing like crazy, Memphis has seen some slight population dips or stagnation in recent years.
People stay for the BBQ and the culture, but the city is definitely in a tug-of-war with its neighbors for growth.
3. Knoxville: The 2026 Relocation Darling
This is the one that's actually surprising people lately. Knoxville has always been the "scruffy little city" near the Great Smoky Mountains, but as of 2026, it is officially one of the top relocation destinations in the entire country.
The population is around 200,000, which seems small compared to the "Big Two," but the rate of people moving in is insane. For every one person who leaves Knoxville, about 1.6 people are moving in. That’s one of the highest ratios in the U.S.

- Proximity to the Smokies: You can be in the national park in 45 minutes.
- The UT Factor: The University of Tennessee drives a huge chunk of the economy and culture.
- The Cost: It used to be way cheaper than Nashville, though that gap is closing fast as inventory disappears.
4. Chattanooga: The "Gig City"
Coming in at number four is Chattanooga, with roughly 195,000 people. It’s almost neck-and-neck with Knoxville.
Chattanooga is famous for having some of the fastest internet in the world (the "Gig City" nickname), which made it a magnet for remote workers long before the pandemic made that a trend. It’s tucked into the mountains and has this incredibly walkable downtown and riverfront. Honestly, if you like the outdoors but want a "techy" vibe, Chattanooga is usually the winner.
5. Clarksville: The Youthful Giant
A lot of people forget about Clarksville, which is a mistake. It’s the fifth-largest city, with over 175,000 residents.
It’s one of the youngest cities in Tennessee, largely because of Fort Campbell. Young military families and veterans often decide to plant roots here because the housing is still relatively affordable compared to the Nashville sprawl. It’s growing fast—really fast. It’s the principal city of its own metro area that spills over into Kentucky.
What’s Really Happening with Tennessee’s Growth?
When you ask what are the biggest cities in Tennessee, you have to look at the suburbs too. Places like Murfreesboro and Franklin are technically "cities," but they are growing so fast they might eventually rival the traditional top five.

Murfreesboro, for instance, is a beast of its own now. With Middle Tennessee State University (MTSU) right there, it’s not just a bedroom community anymore. It’s a legitimate urban center.
The Realities of Living in These "Big" Cities
It’s not all sunshine and low taxes. If you’re planning a move to any of these spots, there are a few things that might surprise you:
- Infrastructure Struggles: The roads in Knoxville and Nashville are struggling to keep up. I’ve heard locals complain that a drive that used to take 20 minutes now takes an hour. Potholes are basically a state mascot at this point.
- Housing Inventory: It is tight. In Knoxville, the 2026 forecast shows home appreciation staying high because there just aren't enough houses for the people moving in from places like California or New York.
- The "Vibe" Shift: Long-time residents in Nashville will tell you the city has lost some of its "soul" to the glitzy new developments. Whether that’s true or just nostalgia is up for debate.
Actionable Takeaways for 2026
If you are looking to move or invest in Tennessee this year, don't just look at the top two.
- For Investment: Look at the "transitional" neighborhoods in Knoxville (like Old North Knoxville) or the northern Nashville suburbs like Hendersonville and Gallatin.
- For Families: Clarksville and Murfreesboro still offer some of the best value-to-amenity ratios in the state.
- For Lifestyle: If you need mountains, it's Knoxville or Chattanooga. If you need a career in a corporate HQ, it's Nashville.
Tennessee is essentially becoming a state of "hubs." Every major city has its own distinct personality and economy. Whether you want the grit of Memphis or the high-speed fiber of Chattanooga, the biggest cities in the state are definitely no longer just small Southern towns. They are becoming major players on the national stage.

Next Steps:
- Identify your priority: Is it job growth (Nashville), outdoor access (Knoxville), or affordability (Clarksville)?
- Research the specific school districts in Williamson and Rutherford counties if you have kids; they are consistently the highest-rated in the state.
- Visit during a "shoulder season" (like late October or April) to get a feel for the local climate and true traffic patterns without the peak tourist crowds.
