Sidney is a town in Montana. The population was 5,191 at the 2010 census.
The area experienced an oil boom and bust in the late 1970s and early 1980s, bringing an influx of people to the town for a short period of time. Around the start of the 21st century, the town started experiencing another surge in oil exploration activity. The entire region has had substantial increase in population. This has brought a tremendous increase in the economy, the population and crime.
Sidney is at the intersection of Highways 200 and 16. It can also be accessed by Hwy 23.
Many workers stay in hotels and campgrounds. Reservations are critical.
