Sublette County is a county in the U.S. state of Wyoming. As of the 2020 United States Census, the population was 8,728.[1] The county seat is Pinedale.[2] It is a sparsely populated rural county in western Wyoming, along the Green River.
Sublette County was created February 15, 1921, of land partitioned from Fremont and Lincoln counties. Its governing organization was completed by 1923.[3] Before settlement, the western Wyoming mountains were traversed and harvested by fur trappers and traders. Sublette County is named for one of those early characters, William Lewis Sublette.[4] Today the county celebrates its fur trade heritage with the Museum of the Mountain Man in Pinedale. In the early 1900s the majority of the population in what is today Sublette County were first generation immigrants from England and Germany. A majority of the population in Sublette County supported America's entry into World War I and at the time the county was known for its "pro-British" sentiments. The German immigrants in the county were not anti-British, and most of them were outspoken about England being their favorite foreign country other than Germany, however they did support neutrality and want America to stay out of the war. Even during the war, relations between first generation English immigrants and first generation German immigrants were known for being exceptionally cordial (Sublette County, Wyoming stood out in this regard because this was not the norm nation-wide).[5]
According to the US Census Bureau, the county has a total area of, of which is land and (1.0%) is water.[6]
At present, Bridger National Forest and Teton National Forest are administratively combined into the Bridger-Teton National Forest. Sublette County contains portions of both original forests.

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.[12]
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 commission to its previous number of three.[13]
