Cora is a census-designated place (CDP) in Sublette County, Wyoming, United States. The population was 142 at the 2010 census.
Cora may have been named after Cora House, an early resident of the area and cowgirl. In the early 20th century the town post office was moved to its current site from a ranch one mile to the East. Dog sleds were used at one time to make winter deliveries to residents who lived in the Cora area and the rest of the Upper Green River valley.
In 2011 the United States Postal Service considered closing the Cora post office for budget reasons. Residents of Cora protested and wrote letters to the USPS requesting that the post office remain open because it serves as a gathering place for the community. As of 2020 the post office is still open.
As of the census of 2000, there were 76 people, 38 households, and 25 families residing in the CDP. The population density was 14.1 people per square mile (5.4/km2). There were 60 housing units at an average density of 11.1/sq mi (4.3/km2).
