Sublette County is a county located in the U.S. state of Wyoming. As of the 2010 census, the population was 10,247.  The county seat is Pinedale.  It is a sparsely populated rural county in western Wyoming, along the Green River.
Sublette County was created February 15, 1921, with land detached from Fremont County and Lincoln County, and organized in 1923.  Historically, the area was important to the fur trade, and the county itself takes its name from one of Wyoming's early fur traders, William Lewis Sublette.  Today the county celebrates its fur trade heritage with the Museum of the Mountain Man in Pinedale.

Like most of Wyoming, Sublette County is overwhelmingly Republican. Since it was created in 1921, the solitary Democrat to carry the county was Franklin D. Roosevelt, who won a majority against Herbert Hoover in 1932 and a twenty-nine vote plurality against Alf Landon four years later. Since 1968 no Democrat has reached twenty-nine percent of Sublette County’s ballots, and the only occasions a Republican has failed to pass seventy percent were when Ross Perot took substantial numbers of votes in 1992 and 1996.
Sublette County is managed by a county commission with three members.
In 2011, Sublette County residents petitioned voters to approve an increase in this number to five as allowed under Wyoming law. The ballot initiative passed and five commissioners were to be seated during the 2012 election cycle. 
In early 2012, another ballot initiative was presented to voters requesting their approval to decrease the number of county commissioners back to three even before seating the two additional commissioners. This second special election, held on May 8, 2012, returned the number of commissioners on the council back to the original number of three.
