Montpelier is a city in Bear Lake County, Idaho, United States.

The city is the largest community in the Bear Lake Valley, a farming region north of Bear Lake in southeastern Idaho along the Utah border.

First it was known as Clover Creek by Oregon Trail travelers, later it became Belmont and finally was given the name Montpelier by Brigham Young, one of the early leaders of the Church of Jesus Christ of Latter-day Saints (LDS Church), after the capital of his birth state of Vermont.
