5 minute walk away from the Ottawa River. It seperates Ontario & Quebec
About 1 mile to the next county, 3 miles from Illinois, 700 from Canada and 800 from Mexico (I live on the south side of the St. Louis area, about 6 miles from the city itself).
5 miles (8 km) due east by northeast from here to the banks of the Potomac, the Maryland state line.
Only done it once, by Cat from the new port in Belfast. Two hours was an approximation, it’s maybe a bit less, but more than 90 mins.
Edit: not Cat, Stena Line cat.
58 miles to the Welsh border, 56miles to the sea and 136 miles to the French coast!
By this measure I’m a bit over 3 hours from France. 2 1/2 hours to Ashford, 35 minutes on the Shuttle through the Channel Tunnel. (In reality add an extra hour for the delays on the M25 around London!)
Only an hour? Must have got better since I lived down there 
About 10 miles north of Georgia.
You could be right - I try to avoid the M25 like the plague :dubious:
Maybe 25 miles from NJ and 20 miles from CT as the crow flies.
Also I’m about a 10 minute walk away from NYC.
About 11 miles west of Indiana.
Husband estimates about 90 miles south of Wisconsin.
County line? About half a block.
Obviously, you’re in the Keys and using driving miles, and not as the crow flies. Then, depending on your exact location, either Cuba or Bimini (Bahamas) would be your closest non-Florida border.
Also, are you denying the statehood of Alabama? 
Alabama is further away..I didn’t want to stretch it. And technically - this is SDMB after all - the title of the thread is “How far do you live from the nearest state (country) line”. I went with state. 
From where I am..I think Bimini is closer than Cuba. I’ll go book a boat and check it out. Be back in a few days!

Idaho panhandle here. 20 miles west to Washington, 18 miles east to Montana and 70 miles north the British Columbia.
You may have close to a minimum distance on three sides of you. Only those further north of your location could beat you.
It has me wondering whose location is the minimum on All Four Sides with different states (or countries) on each side. A gut hunch would be that it would have to be an eastern state, and probably some little weird shaped part of the state at that. VT and NH may wind up with that distinction. Where else might that place be?
If you live at the very northern tip of Delaware, you are very close to three states. But the ocean is to the southeast. That’s the issue with all the tiniest states, they’re all coastal. In the case of DC, it’s so small that it’s completely surrounded by two states.
In Delaware, you could still live pretty close to four states, but you’d have to drive through a closer one to get to the farther one. Does that count?
Also, I don’t know how close any private homes are to the the Four Corners area (AZ, CO, NM, and UT). but in theory you could build a place where a door in each side of your house opens in a different state. Still, technically speaking, you would be residing in one state, have three more extremely close, and have to travel a very long way to get to the next nearest.
Excellent analysis that comes to pretty much the same conclusions I have. Is that Four Corners lot available for a private home, you guess?
As for having to drive across one state to get to the fourth, I suppose we could do that if it produced a minimum 4-sided situation. Maybe we can locate one spot where we don’t have to do that.
I’m ~38 miles from Kentucky, the nearest state line. I’m 519 miles from Windsor, Ontario, the nearest international border. From where I live, it’s ~8 miles to the Trousdale County (TN) line.
Less than half a mile from the New Jersey border.
About 3 miles east of me is the Pennsylvania/ New Jersey line. Not too far to Delaware in tje south.
