Kirby Vermont is a town in Caledonia County, just east of St Johnsbury and Lyndonville, VT. Kirby is located in the beautifully scenic Northeast Kingdom of Vermont, an area that National Geographic selected as part of their geotourism program for sustainable destinations.

The town has never had any villages or post offices. Townspeople receive their mail from the neighboring towns of Concord, Burke or Lyndon. At the few places within the town where two or more roads meet, signs indicate whose house is in each direction, instead of the location of villages.
