Snow King Observatory and Planetarium is a planned astronomy facility on US Forest Service property at the summit of Snow King Mountain in Jackson, Wyoming. In January 2020, Bridger–Teton National Forest administrators released a draft environmental impact statement regarding the proposed facility. A Nevada–Wyoming amateur astronomer, Samuel Singer, created the nonprofit Wyoming Stargazing in 2014 to foster the project. Designer, Jakub Galczynski, joined Samuel Singer in 2015 to design and draft the Snow King Observatory.
The planetarium would be co-housed with a restaurant, ski patrol, and other amenities in a building at the summit. The observatory would be a separate building.
