Nunn is a Statutory Town in Weld County, Colorado, United States. The population was 471 at the 2000 census. The town is small rural agricultural community located on the Colorado Eastern Plains north of Greeley. Somewhat isolated, it is surrounded by flat cultivated countryside of the Colorado Piedmont in area historically known for raising cattle, sheep, sugar beets, beans and potatoes. The town was founded as a shipping point on the Denver Pacific Railroad in the late 19th century and today sits along the western side of U.S. Highway 85 between Greeley and Cheyenne, Wyoming. It consists of a small grid of single-family homes on gravel streets. The town suffered a decline in both its economy and population beginning in the middle 20th century, and today the former storefronts along Logan Street parallel to the highway are largely boarded up. The remaining industry in town consists of a grain elevator and a cafe, as well as several farms on the outskirts of town. A major landmark is a large water tower emblazoned with the words "watch Nunn grow". The remaining economic activity has largely shifted southward to the towns of Pierce and Ault. The town also has a town park and a municipal hall.

In October 2006, Vancouver-based Powertech (USA) Inc. announced preliminary plans to mine uranium by in-situ leaching and possibly open-pit mining from a deposit in sandstones of the Fox Hills Formation several miles west of Nunn.
Some local residents have formed Coloradoans Against Resource Destruction (C.A.R.D.) to oppose the proposed mining. They and a landowners' organization called "Stewards of the Land" (SOTL) point out that the proposed mining area is only six miles northeast of the Fort Collins city limit, and that the Fox Hills Formation is a major water-supply aquifer. C.A.R.D. and SOTL dispute the safety of both in-situ leaching and open-pit mining for uranium.
On July 19, 2007, Powertech held an informational meeting at the Nunn Community Center.
Nunn is the home of Greenfaith Ministry, the nation's first cannabis sacrament church and charity.
