Cloud Creek crater is an impact crater in Wyoming, United States. The crater is located in Natrona County, about 48 miles (77 km) northwest of Casper, near the center of a geological feature known as the Casper Arch.^: 445

The Cloud Creek structure is circular with a current diameter of about 7 kilometres (4.3 mi), and it is buried beneath about 1,200 metres (3,900 ft) of Mesozoic rocks.^: 445 The age of the structure is estimated to be 190 ± 20 million years, which means that it formed as the result of an impact during the early part of the Jurassic Period.^: 445 This impact feature is not exposed at the surface, but it is known only through wells drilled for oil and gas. First reported by Donald Stone, Cloud Creek is a circular structure documented using several 2D reflection seismic lines of fair to good quality, gravity, magnetic and borehole data. The structure has a central core of brecciated, fractured and faulted rocks uplifted up to 520 m relative to the normal stratigraphy outside the structure. The core is surrounded by an annular trough and a detached fault-bounded rim anticline. The rim anticline defines the 7 km diameter of the structure. The structure was compressed and upthrown during the Laramide compression. Morphometric parameters of the structure are consistent with known impact structures. The core is associated with a positive gravity anomaly. Magnetic data could not be interpreted.
