The Sage Sparrow (Amphispiza belli) is a medium-sized sparrow.

This passerine bird is primarily found in the interior of the Western United States (between the Rocky Mountains and the coastal ranges such as the Cascades), ranging a bit down into Mexico, with a Pacific coastal subspecies known as Bell's Sparrow.

Sage Sparrows are indeed often tied to sagebrush habitats, although they can also be found in brushy stands of saltbush, chamnise, and other low shrubs of the arid Interior West. Although their numbers are generally strong at this time, significant declines in sagebrush habitat in the West could be expected to impact Sage Sparrow populations in the near future.

The species' epithet (belli) refers to John Graham Bell.
