Gillette (/ɪˈlɛt/, jih-LET) is a city in and the county seat of Campbell County, Wyoming, United States. The town was founded in 1891 as a major railway town on the Chicago, Burlington and Quincy Railroad.

The population was estimated at 33,496, as of July 1, 2023, making it the 3rd most populous city in Wyoming after Cheyenne and Casper. Gillette's population had increased 48% in the ten years after the 2000 census, which counted 19,646 residents, after a boom in its local fossil fuel industries.

Gillette is centrally located in an area devoted to the development of vast quantities of coal, oil, and coalbed methane gas. The city calls itself the "Energy Capital of the Nation", because Wyoming provides nearly 35% of the nation's coal. However, a decline in coal use in the U.S. in the first quarter of the 21st century has affected the state economy. Some local officials are seeking other industries or employment opportunities. As a major economic hub for the county, the city is also a regional center for media, education, health, and arts.
