Havre (IPA [hævɚ]) is a city in Hill County, Montana, is said to be named after the city of Le Havre in France, although this is disputed by some inhabitants ^{[citation needed]}. The area was originally known as Bullhook Bottoms. The population was 9,621 at the 2000 census. It is the county seat of Hill County^GR6.

Located in north central Montana, it was incorporated in 1893. It was founded primarily to serve as a major railroad service center for James J. Hill with its location midway between Seattle and Minneapolis-St. Paul.

It is the largest city on the Hi-Line and the eighth largest city in Montana. With the nearest major city, Great Falls, about 100 miles to the south, Havre serves as a medical and business center for the Hi Line. U.S. Highway 87 has its northern terminus at Havre. U.S. Highway 2, running east-west, is the city's main street. The largest employers are Northern Montana Hospital, Montana State University Northern, and the BNSF Railway. The Milk River (tributary of the Missouri River) runs through the town, and the Bear Paw Mountains can be seen to the South.

Walking around the streets of Havre one may see a few small grids of purple colored squares on the sidewalk. These are from a sort of underground "mall" built in the city at least a hundred years ago (the squares let in sunlight). Throughout its history, "Havre Beneath the Streets" has been host to a brothel, a Chinese laundromat, a saloon, a drugstore, at least three opium dens, and rooms used for smuggling alcohol during Prohibition.

At the bluffs behind the Holiday Village shopping mall in Havre, is the Wahkpa Chu'gn bison kill. Over 2,000 years old, it is one of the largest and best preserved bison kills anywhere. Also near the buffalo jump, as it is known in Havre, are the Badlands, an arid desert area in the valley near the Hi-Line's major source of water, the Milk River. Fossils and petrified wood can be found in the old sediment. In contrast to the beautiful Bear Paw Mountains to the south that are plentiful and lush during the spring, the Badlands are dry and resemble a desert region, thus making Havre one of the most geolocially diversified areas in Montana.

Six miles southwest of Havre is Fort Assiniboine, which served as one of Montana's principal military posts from 1879 through the Prohibition era. At its peak, the fort housed and employed 489 soldiers in 104 buildings.

Also near Havre is the Bear Paw Battlefield site of the Battle of Bear Paw Mountain, where the Nez Perce were attacked and defeated by the U.S. Cavalry. Chief Joseph surrendered to the Cavalry and making a famous speech ending with the line, “From where the sun now stands, I will fight no more forever.”
