List of municipalities in Montana

[1] Montana is divided into 56 counties and contains 129 municipalities consisting of cities and towns.

[1] Montana's municipalities cover only 1.2% of the state's land mass but are home to 53.8% of its population.

[3] In Montana, municipalities are divided into four classes by state statute based on their population.

Cities and towns are classified at the time of their organization, and are reorganized when they change classification due to an increase or decrease in population.

Under similar exceptions municipalities with a population of between 5,000 and 7,500 may elect by resolution to be either a Second or Third Class city.
