So, you’re looking at a map of Tennessee and realized it’s a lot wider than it looks on a postcard. Honestly, most people underestimate the trek across the Volunteer State. If you're wondering how far is Knoxville TN from Memphis TN, the short answer is roughly 390 miles. But if you’ve ever driven I-40, you know that mileage is only half the story.
You’re basically crossing three different worlds. You start in the Mississippi Delta’s flat, humid plains, cruise through the rolling hills of Middle Tennessee, and end up in the foothills of the Great Smoky Mountains. It's a long haul. You're looking at about 6 hours of seat time if the traffic gods are smiling on you, but let’s be real—between Nashville construction and the occasional tractor-trailer showdown near Jackson, it usually takes a bit longer.
The Brutal Reality of the I-40 Corridor
Most of your journey is a straight shot on Interstate 40. It’s the spine of Tennessee. According to the Tennessee Department of Transportation (TDOT), this stretch is one of the most traveled freight corridors in the country. That means you’ll be sharing the road with a lot of semi-trucks.
If you leave Memphis heading east, you’ll hit Jackson in about an hour and a half. This is usually where people realize they forgot to get gas. From there, it’s another two hours to Nashville. Now, here is the kicker: Nashville traffic is a beast. If you hit the "Music City" loop between 3:30 PM and 6:30 PM, add an extra 45 minutes to your life. Seriously. Once you clear the Nashville sprawl, the drive to Knoxville is actually quite pretty, especially as you climb the Cumberland Plateau.

Breaking Down the Distance by the Numbers
- Total Road Mileage: Approximately 388 to 392 miles depending on your exact start/stop points.
- Drive Time: 5 hours and 45 minutes (pure driving) to 7 hours (with human stops).
- Air Distance: About 366 miles "as the crow flies."
- Time Zone Shift: This is the part that trips everyone up. Memphis is Central Time. Knoxville is Eastern Time. If you leave Memphis at Noon, and it takes you 6 hours to drive, you won’t arrive at 6:00 PM. You’ll arrive at 7:00 PM. You "lose" an hour going east.
Is it Better to Fly or Drive?
Unless you have a private jet or a very specific reason to avoid the highway, most locals just drive. There are no direct commercial flights between Memphis (MEM) and Knoxville (TYS).
If you try to fly, you’ll likely have a layover in Charlotte or Atlanta. By the time you deal with TSA, the layover, and the rental car counter, you could have driven the distance twice. Plus, a last-minute flight can easily run you $400, while a tank of gas is way cheaper.
Where to Stop So You Don't Lose Your Mind
Since how far is Knoxville TN from Memphis TN is nearly a full day's commitment, you’re going to need a break. Don't just settle for a greasy fast-food joint at a gas station.

The Halfway Point: Nashville
Nashville is the obvious choice. If you want a quick leg-stretcher, Centennial Park is right off the path and has a full-scale replica of the Parthenon. It’s weird, it’s cool, and it’s free to walk around outside. If you're hungry, skip the tourist traps on Broadway and hit up Hattie B’s for some hot chicken—just be prepared for a line.
The Hidden Gem: Jackson
About 70 miles east of Memphis, Jackson is a solid spot to stop if you’re already tired. Case Knife Road has some decent local spots, but the real draw is the Casey Jones Home & Railroad Museum. It’s a bit of Americana that breaks up the monotony of the asphalt.
The Cumberland Plateau
Between Nashville and Knoxville, you’ll hit the plateau. The elevation jump is noticeable. If you have an extra hour, take a tiny detour to Burgess Falls State Park near Cookeville. The waterfalls are massive and it’s a great way to shake off the "highway hypnosis."

Winter Travel and Safety
Tennessee weather is moody. In the summer, you're dealing with sudden torrential downpours that turn I-40 into a lake. In the winter, the Cumberland Plateau (near Crossville) often gets snow or ice when the rest of the state just gets rain.
Because of the elevation change, the temperature can drop 10 degrees in a matter of miles. Check the TDOT "SmartWay" cameras before you head out. They provide live feeds of the road conditions, which is a lifesaver if you’re worried about a pileup near the "40/75" split in Knoxville.
Actionable Tips for the Trip
- Gas Up in Jackson or Cookeville: Gas prices in the middle of Nashville are usually inflated.
- Podcasts are Mandatory: You’re going to be in the car for a long time. Download a few hours of audio because cell service can get spotty in the rural stretches between Jackson and Nashville.
- Watch the Time Zone: Set your watch or phone to auto-update. It’s easy to miss dinner reservations in Knoxville because you forgot about the Eastern Time jump.
- Avoid the Nashville Rush: If you can, timing your pass through Nashville for 10:00 AM or 1:00 PM will save you a world of frustration.
Basically, the distance from Memphis to Knoxville is a rite of passage for Tennesseans. It’s a long, straight, truck-filled journey, but seeing the Sunsphere appear on the Knoxville skyline after hours of driving is a pretty great feeling. Just keep your eyes on the road and maybe grab a box of Gibson’s Donuts in Memphis before you start—they make the first 100 miles go by much faster.
To get started on your trip, check the current traffic flow on the I-40 East corridor through the TDOT SmartWay app to ensure no major accidents have closed the lanes near the Tennessee River bridge.
