The sagebrush lizard or sagebrush swift (Sceloporus graciosus) is a common species of phrynosomatid lizard found at mid to high altitudes in the western United States. It belongs to the genus Sceloporus (spiny lizards) in the Phrynosomatidae family of reptiles. Named after the sagebrush plants near which it is commonly found, the sagebrush lizard has keeled and spiny scales running along its dorsal surface.
The sagebrush lizard is similar to the western fence lizard, another Sceloporus species found in the western US. The sagebrush lizard can be distinguished from the western fence lizard in that the former is on average smaller and has finer scales. The keeled dorsal scales are typically gray or tan, but can be a variety of colors. The main (ground) color is broken by a lighter gray or tan stripe running down the center of the back (vertebral stripe) and two light stripes, one on either side of the lizard (dorsolateral stripes). S. graciosus will sometimes have orange markings on its sides.
Three regional races of the sagebrush lizard are recognized: the southern sagebrush lizard lives in Southern California, and the western and northern races are found in many western states, including Nevada, Oregon, Idaho, Colorado, Montana, Washington, New Mexico, Utah, Wyoming, North Dakota, South Dakota, Nebraska, and Arizona.

GBIF citizen-science records
It is estimated from how often the Sagebrush Lizard is recorded against all the reptiles logged in Yellowstone National Park (42 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
