Shell is a census-designated place (CDP) in Big Horn County, Wyoming, United States. The population was 83 at the 2010 Census.
The community is named for the abundance of fossil shells located in the area. Nearby exposed formations such as the Cloverly Formation and the Morrison Formation have yielded numerous fossils of dinosaurs and other animals. Located to the west of the town is the Red Gulch Dinosaur Tracksite, a rare collection of dinosaur tracks from the Jurassic.
Shell is home to the University of Nebraska-Lincoln & Iowa State University geology field station.
