Gas City, Indiana
I’ve been in a state of gas, but not in the State of Gas.
We decided to leave some of the easy ones for the . 
Virginia City, Nevada
There is also a Virginia City in Montana, but confusingly, that one is actually a town.
Another Wyoming in RI. Surely someone could dig up a list of census-designated places and run a quick script.
South west corner, but to this day no one has ever been there!
ETA: One would be hard pressed to locate the “south east corner” of MA.
It sure does!
I’m not feeling all that smart, either! And I grew up Upstate, too.
I am interested in towns also.
Wow I didn’t realize there were so many. But I should have guessed that there would be alot of Washingtons.
Yes I am. That should yield many more.
So does Nevada TX, I believe.
Pennsylvania has the Wyoming Valley which should get bonus points because the state is actually named after it, for reasons I’ve never entirely understood.
I wouldn’t be a true Doper if I didn’t let my inner snark come out and play. 
There’s a Maryland Line, Maryland
Maybe another question is if there are any states that have no city named for it.
For example, I don’t think there is a New Mexico City, or New Hampshire City.
Wisconsin Dells, WI
Wisconsin Rapids, WI
Not a city or town, so, sorry it doesn’t count. I did find Wyoming Valley in Kirby Park. Wyoming Valley, near Wilkes-Barre.

Hey that rhymes.
Idaho City, Idaho; a city in name only, with a permanent population of less than 500. At one time in the 19th century it actually was a city… largest or second-largest or something in the Pac-NW thanks to a late gold boom. Then the big timber interests moved in creating a few years of faux-prosperity until the old growth was logged out. A sad story repeated ad infinitum all around the rural west.
Today it’s the county seat of a bankrupt county that can hardly keep its schools open or the roads paved. Still an interesting place though; I own a share in a placer-mining claim in the area, go there a couple of times a year for a little R & R and… who knows… maybe even a chance to strike it rich…
It’s just NE of Boise. And it’s on the map. I’ll take it!

I ran a quick search using Mathematica and the geographic data servers of Wolfram. If we restrict ourselves to cities and towns whose names are exactly those of states, here’s what we have:
[ul][]Oklahoma, PA[]California: California, MD & 3 smaller cities[]Texas, WI[]Nevada, MO & 3 smaller cities[]Indiana, PA[]Virginia, MN & 2 smaller cities[]Alabama, NY[]Iowa, LA[]Vermont, LA[]Georgia, VT[]Florida, NY & 4 smaller cities[]Wyoming, MI & 9 (!) smaller cities[]Tennessee, IL[]New York, NY[]Oregon, OH & 3 smaller cities[]Kansas, OK & 2 smaller cities[]Ohio, NY & 1 smaller city[]Delaware, OH & 3 smaller cities[]Maine, NY & 2 smaller cities[]Montana, WI[]Maryland, NY[]Louisiana, MOWashington, DC & 31 smaller cities[/ul]Any state that’s not on this list does not have a city named after it, or at least not one in Wolfram’s database. If I’ve counted right, there are 27 such states, although eight of those are states with two-word names like “New Hampshire”.
